#"450 g"# of hydrogen gas reacts with an excess of nitrogen gas to produce #"15.75 g"# of ammonia. What is the percent yield?
1 Answer
The percent yield of ammonia is
Explanation:
In order to determine percent yield, the theoretical yield must first be calculated. This is done by converting the mass of the limiting reactant to moles, then multiplying times the mole ratio from the balanced equation that has ammonia on top and hydrogen on the bottom. Once the theoretical yield is calculated, the percent yield is determine by the following equation:
Start with a balanced equation:
Since nitrogen is in excess, the limiting reactant is hydrogen. The molar mass of
Convert the mass of
Determine the theoretical yield of ammonia by multiplying mol
The theoretical yield of ammonia in this reaction is
The actual yield is
The percent yield is
