Question

what is percentage yield ?

Answer 1

The yield of a reaction is the actual mass of product obtained. The percentage yield can be calculated: For example, the maximum theoretical mass of product in a certain reaction is 20g, but only 15g is actually obtained. percentage yield = 15⁄20 × 100 = 75%

Answer 2

answer :-

the percentage yield of product = actual yield / the theoretical maximum yieled × 100. the actual amount of any limiting reagent consumed in such incomplete reactions is given by [ % yield × given moles of limiting reagent ] [ for reversible reactions ].

for irreversible reaction with % yield less than 100 , the reaction 8s not fully converted to product and it's unused part is waste.
