If you have 4.44 x 10(25) atoms of calcium chloride how many grams is that?
If you have 4.44 x 10(25) atoms of calcium chloride how many grams is that (the 25 in brackets is suppose to show that the 25 is smaller than the ten)
Asked by Dung Ellenwood 6 months ago.
Calcium chloride doesn't come in atoms. It is a molecule. So supposing the question to be: "If you have 4.44 x 10(25) molecules of calcium chloride...". (The alternative would be "If you have 4.44 x 10(25) atoms of calcium and chlorine in the ratio 1:2 ..." which would give an answer one-third that of what follows here.) (4.44 x 10^25 molecules) / (6.023 x 10^23 molecules/mol) x (110.9848 g CaCl2/mol) = 8182 g CaCl2 Answered by Alonzo Oesterle 6 months ago.
What volume of acetylene measured at standard conditions could be obtained from 10 grams of calcium chloride?
Asked by Pamila Rohm 6 months ago.
The reaction is : CaC2 + 2 H2O >> C2H2 + Ca(OH)2 Molecular weight CaC2 = 64 g/mol 10 g / 64 = 0.156 mole of calcium carbide ( not calcium chloride ) The ratio between CaC2 and C2H2 is 1 : 1so we would get 0.156 mole of C2H2 At STP : T = 273 K and p = 1 atm V = nRT / p = 0.156 x 0.0821 x 273 / 1 = 3.5 L of C2H2 Answered by Boris Meis 6 months ago.
You mean, of course, calcium carbide, CaC2. CaC2 + 2H2O ----> C2H2 + Ca(OH)2 Now you can work out the volume yourself. Answered by Henry Boelke 6 months ago.
How to make 10 mM CaCl2 from Calcium Chloride Dihydrate with molar mass 147.02 g/moles?
Asked by Susanne Marantz 6 months ago.
10 mM means 10 millimoles = 0.01 mole Calcium Chloride Dihydrate = CaCl2 * 2 H2O One mole of Calcium Chloride Dihydrate contains one mole of CaCl2 and 2 moles of H2O. Let’s determine the mass of CaCl2 in one mole of CaCl2 * 2 H2O. Mass of 2 moles of H2O = 36 g Mass of 1 mole of CaCl2 = 147.02 – 36 = 111.02 Mass of 0.01 mole = 1.1102 grams of CaCl2 Answered by Ezequiel Budney 6 months ago.

Calculate osmolarity, freezing point, and boiling point of a solution prepared by dissolving 10.4 g of calcium chloride in 250 g of water?
How much water would you need to add to the above solution to make it isotonic?
Asked by Jeniffer Sigala 6 months ago.
Calcium chloride = CaCl2 and CaCl2 ==> Ca^2+ + 2Cl^- 10.4 g CaCl2 x 1 mol/111 g = 0.0937 moles CaCl2 Assuming a density of H2O of 1 g/ml, then... Osmolarity = 0.0937 moles/0.25 L = 0.375 molar = 0.375 x 3 = 1.125 osmolar (3 ions) To calculate freezing and boiling point, first calculate molality (moles/kg) molaliry = 0.0937 moles/0.25 kg = 0.375 molal Since there are 3 ions after dissociation, the van't Hoff factor (i) is 3 Freezing point: ∆T = imK = (3)(0.375)(1.86) = 2.1ºC so new freezing point = -2.1ºC Boiling point: ∆T = imK = (3)(0.375)(0.52) = 0.59ºC so new boiling point = 100.6ºC Answered by Page Marriot 6 months ago.

A small homework problem. If you could include the steps that would be awesome. I tried it and got 40,034 grams, but that seems wrong. Thanks a ton!!
Asked by Georgann Frechette 6 months ago.
.217 x 10^27 molecules divided by 6.02 x 10^23 is equal to the number of moles of the substance. Now multiply that by the molecular mass. The formula is CaCl2. Answered by Signe Valenzano 6 months ago.

calculate the milliosmoles of calcium chloride (mw= 147) in 147ml of a 10% calcium chloride Solution?
Asked by Majorie Vales 6 months ago.
Assuming density of solution to be same as water, 147mL of 10% Calcium Chloride solution would contain 14.7 grams Calcium Chloride. Since molecular weight of Calcium Chloride is 147 grams per mole, therefore 14.7 grams is equivalent to 0.1 mole. Now, coming to Osmoles. In solution, each molecule of Calcium Chloride dissociates to form one calcium ion and two chloride ions, hence producing 3 ions. CaCl2 -> Ca++ and 2 Cl- So, a solution containing 0.1 mole Calcium Chloride will produce 0.3 mole of ions which is same as 0.3 osmoles. 0.3 osmoles = 300 milliosmoles.
