A solution of NaCl(aq) is added slowly to a solution of lead nitrate, Pb(NO3)2(aq), until no further precipitation occurs. The precipitate is collected by filtration, dried, and weighed. A total of 16.37g PbCl2(s)s obtained from 200.0 mL of the original solution. Calculate the molarity of the Pb(NO3)2(aq) Pb(NO3)2 (aq) solution.
