Percent Yield Calculator

Compare actual yield to theoretical yield.

Actual yield

Theoretical yield

Percent yield (%) 82

Formula: percent yield = actual ÷ theoretical × 100

Step-by-step with your numbers:

1. Values used:

2. Actual yield = 8.2

3. Theoretical yield = 10

5. Percent yield = Actual yield x Theoretical yield = 8.2 x 10 = 82%

Did we solve your problem today?

How efficient a reaction was, comparing what you got to the maximum possible.

The math behind it

percent yield = actual yield ÷ theoretical yield × 100.

8.2 g of 10 g possible → 82%.

Over 100%?
