Can you calculate the percent by mass of sulfur in each?
Can you please show me step by step on how to get these answers? Na2SO4, sodium sulfate Al2S3, aluminum sulfide SO3, sulfur trioxide C2H6SO, dimethylsulfoxide, topical anti-inflammatory C10H10N4O2S, sulfadiazine, antibacterial

I won't do each of them but I will show you how to do one and you can do the rest. It's really easy. 1. calculate the total mass of the compound. 2. Calculate the amount of sulfur in the compound. 3. Use the following equation to calculate percent by mass. (Mass Sulfer)/(Mass Compound) X 100 For the first compound: 1. Mass compound = 2*(MW Na) + (MW S) + 4*(MW O) = 142.04 2. Mass Sulfur = 1*(MW S) since theres only one sulfer in the compound. = 32.06 3. Therefore % Sulfer is: (32.06)/(142.004) X 100 = 22.58% sulfur.

Mass Of Sulfur Trioxide Answered by Felicidad Leveque 2 years ago.
exceptionally basic to do. Calculate how plenty that total molecule weighs. Then calculate how plenty each of them one after the different weighs and divide the guy by making use of the finished, then multiply x a hundred to get your share. keep in mind that S and O are interior the parenthesis for 2, so which you have 2 Sulfurs and eight Oxygens interior the molecule (multiply the mass by making use of that then divide by making use of the finished). i could do this even though it extremely is extremely previous due and that i've got not got a periodic table interior attain, yet that could get you thru. wish this helps.
