How do you calculate the number of moles of iron?

We simply divide the five grams by the molar mass of iron. Molar mass is defined as the number of grams in one mole of a given element. Iron has a molar mass of 55.84 grams/mole. So, five grams divided by 55.84 grams/mole gives us 0.089 moles of iron.

How do you find the moles of an element in a compound?

Divide the mass of the compound in grams by the molar mass you just calculated. The answer is the number of moles of that mass of compound. For example, 25 grams of water equals 25/18.016 or 1.39 moles.
