Determine the percentage yield if the expected yield of 
in the above reaction is 40.911 grams but the actual yield is 35.322 grams.
Determine the percentage yield if the expected yield of
In chemistry, percentage yield is a term used to quantify the efficiency of a chemical reaction. In order to calculate this quantity, the value for the actual yield and theoretical yield is needed. The actual yield is the amount of product obtained during a chemical reaction. The theoretical yield is the maximum amount of product possible to be obtain by a chemical reaction which is based on the amount of reactants used. Below is the formula needed to calculate the percentage yield.

0.0031 moles of 
was reacted with 0.0071 moles of 
giving an actual yield of 0.1733 grams of 
. What is the percent yield of this reaction?
0.0031 moles of
is the limiting reactant because based on the equation, 
and 
react in a 1:1 mole ratio. However, there is 0.0040 moles more of 
than 
present. Therefore the amount of 
produced is limited by the amount of 
present in the reaction. Based on the equation, for every 1 mole of 
reacted, 1 mole of 
was produced:
Therefore,
Therefore,
