Suppose we have a solution of lead nitrate, Pb(NO3)2(aq). A solution of NaCl(aq) is added slowly until no further precipitation of PbCl2(s) occurs. The PbCl2(s) precipitate is collected by filtration, dried, and weighed. A total of 12.79 grams of PbCl2(s) is ob- tained from 200.0 milliliters of the original solution. Calculate the molarity of the Pb(NO3)2(aq) solution.
