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
4. Calculate the percent yield
