The actual yield of a certain reaction is 44.0 g, while the theoretical yield is 50.0 g. Calculate the percent yield.
Goshia [24]
Percent yield represents to what extent the reaction runs to completion. In this, the theoretical yield is 50 grams (100% completion).

To calculate percent yield, divide the actual by the theoretical. In doing so, the percent yield is 88% (44/50).
