Final answer:
The percent yield is 80.71%.
Step-by-step explanation:
To calculate the percent yield, we need to use the formula:
Percent Yield = (Actual Yield / Theoretical Yield) * 100
In this case, the actual yield is 1.13 mol and the theoretical yield is 1.40 mol. Plugging these values into the formula:
Percent Yield = (1.13 mol / 1.40 mol) * 100
Percent Yield = 80.71%
