The percent yield of a reaction can be calculated by dividing the actual yield by the theoretical yield and multiplying by 100. In this case, the percent yield of aluminum oxide is 61%.
To calculate the percent yield, we need to compare the actual yield of aluminum oxide to the theoretical yield. The percent yield is given by the formula:
Percent Yield = (Actual Yield / Theoretical Yield) * 100
In this case, the theoretical yield of aluminum oxide is given as 0.900 mol and the actual yield is 0.549 mol. Plugging these values into the formula, we get:
Percent Yield = (0.549 mol / 0.900 mol) * 100 = 61%
Therefore, the percent yield of aluminum oxide is 61%.
