We will learn how to calculate the molar mass of a compound by using its chemical formula. Molar mass is a quantity that is very similar to molecular mass, molecular weight, formula mass, and formula weight. In order to calculate molar mass, we look at the formula to determine how many atoms of each type are in it, and then look at the periodic table to determine the atomic mass of each of the atoms. We will look at compounds containing polyatomic ions, and also hydrate compounds.

So glad I found your channel! I'm a visual learner so how you place everything out has helped me a ton! quick question when I did the last calculation for MGSO4*7H2O I got 246.52g/mol.. Is it ok to be off by a bit like that? 24.31+32.07+64.00+14.14+112.00= 246.52...Or is there something I did wrong?

@JibHyourinmaru 9 лет назад
