You need to calculate the molecular weight of fluoxymesterone first, which I will label as x here. And since all of the following answers are based off of this number, I will use A, B, C for anything that has an answer dependent on x or a previous answer. calculate the moles of fluoxymesterone: 17mg x 1g/1000mg x 1mol/x g = A mol of fluoxymesterone. calculate the molarity of the stock solution: A mol fluoxymesterone / 0.5 L = B M. calculate how much fluoxymesterone is in your aliquot: 100uL x 1L/1000000 uL = 0.00001 L x B mol/L = C mol of fluoxymesterone present in your aliquot. calculate the final solution in terms of molarity: C mol/0.1L = D M.

Answered by Isidro Leisner 6 months ago.

You dilute 0.1 mL ( 100 uL )to 100 mL which is a 1/1000 dilution so the resulting molarity is 1.01 X 10^-4 X 1/1000 = 1.01X10^-4 X 10^-3 = 1.01 X 10^-7 M =0.101 uM This is the part i don't understand. Why are you diluting .1mL? The 1:1000 ratio is throwing me. an aliquot is just a part of a solution, so do you assume its in the same units as the rest (mL?) If so, thats a .1 L aliquot of the 1.01e-4 M solution being diluted more, but it says to a "final volume of 100mL." that doesn't necessarily mean you're adding 100mL of water to the 1.01e-4 M solution, does it? Answered by Dovie Rippe 6 months ago.

OK fluoxymesterone has a molecular weight of 336.4 grams/mole so if one dissolves 17 mg = 0.017 grams in 500 mL 0f water this will be 0.017grams/336.4 grams = 5.05 X 10^-5 moles in 500mL Molarity of original = moles /L= 5.05 X 10^-5 moles/0.5 L = 10.1 x 10^-5 M = 1.01 x 10^-4 M of stock. You dilute 0.1 mL ( 100 uL )to 100 mL which is a 1/1000 dilution so the resulting molarity is 1.01 X 10^-4 X 1/1000 = 1.01X10^-4 X 10^-3 = 1.01 X 10^-7 M =0.101 uM Answered by Renee Gunnarson 6 months ago.

You need to calculate the molecular weight of fluoxymesterone. Once you have that, you multiply mass of fluoxymesterone by the ratio (1 mole / X grams) to get moles of fluoxymesterone. Then, you use the formula M(1) x V(1) = M(2) x V(2). Good luck! Answered by Bronwyn Weinger 6 months ago.

preliminary quantity circumstances preliminary concentration = very final quantity circumstances very final concentration MiVi = MfVf that's the equation you will use the main for dilution issues. M = Molarity V - quantity i = preliminary (what you initiate with) f = very final (what you end with) in case you have 3 of the solutions, you may rearrange the equation so as that the single you don't be attentive to is via itself on one edge of the equation. Then plug interior the values which you be attentive to and you will possibly have your answer. desire this facilitates~ Answered by Shannan Voliva 6 months ago.

A 1M solution contains the gram molecular weight of substance per 1 litre of solution. Molecular weight of fluoxymesterone = 336.444 g/mol. Therefore, 1M fluoxymesterone = 336.444 g/L. Your first solution is 500.0 mL, so 1M fluoxy. is also equal to (336.444 / 2) g/500 mL, that is, 168.222 g/500 mL. Converting this to mg, 1M fluoxy. = 168,222 mg/500 mL. But only 16 mg were dissolved, so molarity of this first solution is : 1 * (16 / 168,222) = 9.511*10^(-5) M. Now 100.0 uL (which is 0.1 mL), is diluted to 100.0 mL. This is a dilution of 0.1/100.0 = 1/1000. Thus, final concentration = 9.511*10^(-5) * 1/1000 = 9.5*10^(-8) M. Answered by Nathalie Hulan 6 months ago.

Medicare..is the only outlet Im gonna sound like a harsh prick, and most drs will tell you the same.I apologize ahead of time, I only wish to help you see the logic of others in the medical feild. You mother is 92 years old, unless the cancer will kill her for sure, ..I do not know how severe it is, but when you are 92 you need to weigh your options, are you really gonna die from the cancer...probably not..she will probably pass from natural causes. Any good dr. or oncologist will tell you this before they give you the option of treatment. I know because this was the case with my grandpa and his prostate cancer..He was 91 years old and was freaking out that he was gonna die from it, the doctor said look you are 91...you are gonna die from something else long before you will die from cancer...He did too about 2 years later he collapse from aortic aneurism and died instantly. Now if she is already going to for sure pass from it then of course by all means do everything you can to accomodate her.. Again you did not state if she had it, or if she was dying from it, becuase the too are very differant. now Halotestin is the generic name for fluoxymesterone. It is a hormone agent /chemo agent that is used for palliative treatment. Palliative treatment means to ease the suffering.. It is not a cure, it does not cure cancer, you may or may not know this, i am just clarifying for you.. This drug they are trying to prescribe you is to ease her suffering as she passes. There are other ways of doing this such as pain pills etc etc. However the pain from cancer can easily out weight the pain medication. Again I dont know were she is at with it. It is a very expensive drug, and if you do not have insurance unfountaly we live in a country that doesn't take good care of its people who are sick or dying. If you feel you need to have this drug, look at pharmacies in canada; where medical treatment is free if you are a citizen, YES FREE or in mexico where the drugs are cheaper. Im sorry for your situation, no one wants to lose their mother. Its tough and I did not mean to offend you...i want to tell you the truth, that most are probably to afraid to tell you..and so that you are not assuming they are tryng to tell you their is a cure, that is right out of your reach.(financially) Again the goal is not to put her through any treatment of anything that is gonna cause more pain the pleasure for the time she has left.

If she's 92, then she's on medicare also. She should have a prescription drug plan. There may also be the same kind of drug, cheaper. Answered by Danae Steinbrook 6 months ago.

A standard solution is prepared for the analysis of fluoxymesterone (C20H29FO3), an anabolic steroid. A stock solution is first prepared by dissolving 18.0 mg of fluoxymesterone in enough water to give a total volume of 500.0 mL. A 100.0 µL aliquot (portion) of this solution is diluted to a final volume of 100.0 mL. Calculate the concentration of the final solution in terms of molarity. Answered by Nestor Ostergard 6 months ago.

the equations you need to use are C = n/V where C= concentration, n= number of moles, V = volume n = m/M where n= number of moles, M = molar mass, m = mass C1V1 = C2V2 where (the 1s are subscripts) C1 = concentration 1 or initial concentration V1 = initial volume and C2V2 are obviously final volume and concentration steps: 1) find the number of moles of fluoxymesterone from the given mass, you can determine the molar mass by a periodic table 2) find the initial concentration 3) remember to convert all the units so they match, so either convert mL to L or vice versa and mg to g before finding the number of moles 4) use the last equation to find the final concentration by rearranging to isolate C2. sorry would have done the question for you, but you wont learn anything that way and also i dont like converting stuff.

Answered by Eldon Eagle 6 months ago.

Firstly, I think you mean 100 μL aliquot (not 100 L aliquot), and secondly, I don't get quite the same decimal answer as the book. Molar mass of C20H29FO3 = 336.4 g/mol. Therefore, by definition, 1 M fluoxymesterone = 336.4 g/L, which, after division by 2, is equal to 168.2 g/500.0 mL. 10.0 mg = 10.0/1000 g. By direct proportion, if 168.2 g (in 500.0 mL) is equivalent to 1 M, then 10.0/1000 g (in 500.0 mL) is equivalent to (10.0/1000)*1/168.2 M, which equals 5.9*10^-5 M. 100 μL in 100.0 mL is a dilution of 100/(100.0*1000) = 1/1000. Thus, final concentration = 5.9*10^-5 * (1/1000) = 5.9*10^-8 M. Answered by Shad Stahl 6 months ago.

AP Chemistry and AP Biology are excellent courses for the well being science careers. Physics no longer a lot. I was, such as you, seeking to decide between those two courses. I had to ask myself: Which type is more regarding my profession? What classification am I higher at? And i selected to do AP Biology. When you consider that you are a sophomore, is there any likelihood that you can take the opposite classification (apart from the one you chose) senior 12 months? So one can make the choice a bit of simpler. I propose possibly doing AP Bio junior 12 months and AP Chem (which uses both Bio and Chemistry) senior yr. AP Biology is just not fairly as difficult as AP Chemistry. Schools generally put more stress on the junior year of high tuition, so taking the easier substitute is an efficient option so that your GPA/classification rank will not be messed up.
