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 18.55 g PbCl₂ (s) is obtained from 200.0 mL of the original solution. Calculate the molarity of the Pb(NO3)₂(aq) solution.

Step 1
The balanced chemical equation for the reaction between NaCl and Pb(NO3)2 is:
Pb(NO3)2(aq) + 2 NaCl(aq) → PbCl2(s) + 2 NaNO3(aq)
From the equation, we see that one mole of Pb(NO3)2 reacts with two moles of NaCl to form one mole of PbCl2.
