The percent yield of a reaction can be calculated using the following formula:Percent Yield = Actual Yield / Theoretical Yield x 100In this case, the actual yield is 5.5 grams, and the theoretical yield is 9.2 grams. Plugging these values into the formula, we get:Percent Yield = 5.5 / 9.2 x 100Percent Yield = 0.5978 x 100Percent Yield 59.78%So, the percent yield of the reaction is approximately 59.78%.
