1.    Finding the mass of atoms, compounds and molecules

2.    Finding the mass of products from a reaction

3.    Finding the percentage of an element in a compound

4.    Finding the empirical formula from a reaction

5.    Finding the molecular formula of a compound

6.    Finding the volume of a gas

7.    Finding the mass or volume from electrolysis
