If the percentage yield of a reaction was 78.51% and the theoretical yield was 288.0 g, what was the actual yield?

%yield (actual yield/theoretical yield)*100

Substitute and solve for actual yield.

226

To find the actual yield of the reaction, you can use the formula:

Actual yield = Percentage yield * Theoretical yield

Plugging in the values given,

Actual yield = 78.51% * 288.0 g

Now, to calculate the answer, you need to convert the percentage to a decimal by dividing it by 100:

Actual yield = 0.7851 * 288.0 g

Calculating further,

Actual yield ≈ 226.2968 g

Therefore, the actual yield of the reaction is approximately 226.3 g.
