A worker reacts 86.3 g of Zn with nitric acid and evaporates the remaining water to obtain 102.5 g of Zn(NO3)2. What are the theoretical yield, the actual yield, and the percent yield? The molar mass of Zn is 65.39 g/mol and the molar mass of Zn(NO3)2 is 189.41 g/mol.

The balanced equation is: Zn + 2HNO3 --> Zn(NO3)2 + H2
