How to use Percentage Yield Calculator:

According to the formula, it requires two values, first is the Theoretical Yield and the second is Actual Yield.

Example :

$$2\text{AL}\;+\;6\text{HCL}\;\rightarrow\;2\text{ALCL}_3\;+\;3\text{H}_2$$

95 g of hydrochloric acid are reacted with excess aluminum producing 2.2 g of hydrogen gas.What is percentage yield?

Solution :

Calculate theoretical yield :

Next, Calculate % Yield :

$$\text{Percentage Yield}\;=$$

$$\frac{\text{Actual}}{\text{Theoretical}}\;*\;100$$

$$\text{Percentage Yield}\;=$$

$$\frac{2.2g\;\text{H}_2}{2.6g\;\text{H}_2}\;*\;100$$

$$\text{Percentage Yield}\;=\;8.6 % $$
