96. Zinc is more active chemically than is silver; it can be used to remove ionic silver from solution.

Zn(s) + 2AgNO3(aq) → Zn(NO3)2(aq) + 2Ag(s)

The concentration of a silver nitrate solution is determined to be 1.330 mol/L. Pieces of zinc totaling 100.0 g are
added to 1.000 L of the solution; 90.0 g of silver is collected.
a. Calculate the percent yield of silver.
b. Suggest a reason why the yield is less than 100.0%.
