Lots and lots and lots of practice problems with mole ratios. This is the first step in learning stoichiometry, for using a chemical equation to get mole ratios and using conversion factors and dimensional analysis on products and reactants.

The calculations steps will be used when the reactants are given in moles and the products need to be displayed in moles.

The calculations steps will be used when the reactants are given in moles and the products need to be displayed in grams (or mass).

The calculations steps will be used when the reactants are given in mass and the products need to be displayed in moles.

This video will show you one of the most common and powerful things a chemist can do: predict the mass of a product, given the reactant masses.
