In Part A, we saw that the theoretical yield of aluminum oxide is 0.800 mol. Calculate the percent yield if the actual yield of aluminum oxide is 0.456 mol.

Percent Yield is the actual practical yield of a certain chemical reaction. It is always less than the theoretical yield calculated due to human handling and error.

Percent Yield = (Actual yield / theoretical yiield) * 100 = (0.456 / 0.800) * 100 = 57%

The yield here is small which means a bad handling and high error.
