How Do You Convert Moles to Grams?

The number of moles present in a compound is often given to the student in the problem. If it is not, then it can be found by looking at the chemical reaction and using the stoichiometric coefficients.

For the compound in question, calculate the molar mass by using a periodic table.

Multiply the number of moles in the compound by the molar mass of the compound. The moles cancel out, and the final answer is in grams.
