How to convert moles into mass?

To convert moles into mass, we first need to find the molar mass of the compound given. This can be done by looking at the mass of each element in the periodic table and then multiplying each mass by the number of atoms of that element in the compound. Molar mass has the units grams/mol which allows to convert between moles and grams.

To go from moles to grams, we need to multiply the number of moles by the molar mass. Let's look at the units: moles * grams/mols = moles will cancel giving us grams only.

Let's now look at an example

Example: What is the mass, in grams, of 1.223 mol of iron(III) sulfate?
