Stoichiometry is the quantitative study of chemical changes.

The most common type of stoichiometry calculation is a mass-mass problem.

A mass-mass problem looks something like this:

"Given this amount of reactant, how much product will form?"

The 6 teps used to solve a mass-mass problem:

1. Write a balanced equation for the reaction.
2. Write the given mass on a dimensional analysis form.
3. Convert mass of reactant to moles of reactant.
4. Convert moles of reactant to moles of product.
5. Convert moles of product to grams of product.
6. Pick up the calculator and do the math.
