Final answer:
The percent yield of the experiment is 100%
Step-by-step explanation:
The percent yield of a reaction can be calculated using the formula:
Percent Yield = (Actual Yield / Theoretical Yield) x 100%
In this case, the actual yield is given as 0.25 mol and the balanced equation tells us that the stoichiometric ratio between Xe and XeF4 is 1:1. Therefore, the theoretical yield would also be 0.25 mol.
Using the formula, we can calculate the percent yield:
Percent Yield = (0.25 mol / 0.25 mol) x 100% = 100%
