# For the reaction,#2x#+#3y#+#4z## rarr## 5w# Initially if 1 mole of #x#,3 mole of #y# and 4 mole of #z# is taken and 1.25 mole of #w# is obtained then what is the % yield of this reaction?

##### 1 Answer

The percent yield is 50 %.

#### Explanation:

This is a **limiting reactant** problem.

We know that we will need a balanced equation and moles of each reactant.

**1. Gather all the information** in one place with the experimental number of moles below the formulas.

**2. Identify the limiting reactant**

An easy way to identify the limiting reactant is to calculate the "moles of reaction" each will give:

You divide the moles of each reactant by its corresponding coefficient in the balanced equation.

I did that for you in the table above.

**3. Calculate the theoretical yield of #w#**

**4. Calculate the percent yield**
