## How to Find the Limiting Reagent

### Method

Divide the moles of each reactant by its stoichiometric coefficient. The reactant with the **smallest ratio** is the limiting reagent.

**Ratio = moles / coefficient**

计算示例

2 mol A and 3 mol B react with coefficients 1A + 2B.

  1. Ratio A = 2 / 1 = 2
  2. Ratio B = 3 / 2 = 1.5
  3. B has the smaller ratio, so B is the limiting reagent
