You must use stoichiometry based on a balanced chemical equation — i.e. the mole ratios given by the equation.

Typical steps:
1. Write and balance the chemical equation.
2. Convert given masses/volumes to moles (use molar volume for gases or molar mass for solids/liquids).
3. Use the mole ratio (from the balanced equation) to calculate moles of other reactants/products.
4. Convert moles back to desired units (grams, liters, molecules).
5. Check for a limiting reagent and, if needed, calculate percent yield.

In short: a balanced equation and mole ratios (stoichiometry).
