Question

3NO2 + H2O -> 2HNO3 + NO
Calculate the percent yield for the following reaction if 76.8 g of H2O reacted and 125 g of NO were produced.

Answer 1

mols H2O = grams/molar mass
Using the coefficients in the balanced equation, convert mols H2O to mols NO.
Convert mols NO to g. g NO = mols NO x molar mass NO. This is the theoretical yield (TY). The actual yield (AY) is 125g.
% yield = (AY/TY)*100 = ?

Answer 2

25%
