Describe a general plan for solving all stoichiometry problems in four steps.

1. Predict balanced chemical reaction. 2. convert whatever you are given into moles.... 3. multiple by the mole ratio, which gives you moles of the desired substance....... 4. convert the moles into the units that you need for your final answer
