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.
