The image above represents percentage yield.

To compute the percentage yield, two essential parameters are needed and these parameters are **actual yield** and **theoretical yield.**

The formula for calculating percentage yield:

%Yield = (^{Actual Yield} ⁄ _{Theoretical Yield}) x 100

Let’s solve an example;

Find the percentage yield when the actual yield is 12 with a theoretical yield of 26.

This implies that;

Actual yield = 12

Theoretical yield = 26

%Yield = (^{Actual Yield} ⁄ _{Theoretical Yield}) x 100

%Yield = (^{12} ⁄ _{26}) x 100

%Yield = 0.46 x 100

%Yield = 46.15

Therefore, the **percentage yield** is **46.15**.

**Calculating the Actual Yield when the Percentage Yield and the Theoretical Yield is Given.**

Actual yield = ^{%yield x theoretical yield} / _{100}

Let’s solve an example;

Find the actual yield when the %yield is 52 with a theoretical yield of 10.

This implies that;

%yield = 52

Theoretical yield = 10

Actual yield = ^{%yield x theoretical yield} / _{100}

Actual yield = ^{52 x 10} / _{100}

Actual yield = ^{520} / _{100}

Actual yield = 5.2

Therefore, the **actual yield** is **5.2.**

**Calculating the Theoretical Yield when the Percentage Yield and the Actual Yield is Given.**

Theoretical yield = ^{%yield x actual yield} / _{100}

Let’s solve an example;

Find the theoretical yield when the %yield is 60 with a actual yield of 8.

This implies that;

%yield = 60

Actual yield = 8

Theoretical yield = ^{%yield x actual yield} / _{100}

Theoretical yield = ^{60 x 8} / _{100}

Theoretical yield = ^{480} / _{100}

Theoretical yield = 4.8

Therefore, the **theoretical yield** is **4.8.**
