Two Parts:
A chemist mixes a solution containing 33.14 g of Pb(NO3)2 with a second solution containing 12.82 g of NaCl. The chemical reaction is:
Pb(NO3)2 (aq) + 2 NaCl (aq) ----> PbCl2 (s) + 2 NaNO3 (aq)
a) Calculate the theoretical yield of PbCl2. (Hint: You first need to find the limiting reactant)
b) The chemist actually collects 23.65 g of solid PbCl2 . Calculate the percent yield.
