Calculating Molar Mass From a Molecular Formula.

Calculating molar mass is the focus of this video. It is critical that all chemistry student know how to calculate molar mass. Indeed, the calculation of molar mass is a fundamental problem in all chemistry classes. To calculate molar mass it is first necessary to know how to find the atomic mass of each element in a molecular formula. Remember the atomic masses of each and every element are found on the periodic table of the elements. Atomic mass and molar mass share the same value (number) but the units for molar mass are grams per mole (g/mole).

Being able to calculate molar mass is an important skill in chemistry. The better you understand how to do this type of problem the easier a lot of other chemistry problems will be for you!

Answers to end of video problems:
Ca(OH)2 = 74.09 g/mole
(NH4)2SO4 = 132.14 g/mole
