A solution of NaCl(aq) is added slowly to a solution of lead nitrate, Pb(NO,),(aq), until no further precipitation occurs. The precipitate is collected by filtration, dried, and weighed. A total of 15.67 g PbCl, (s) is obtained from 200.0 mL of the original solution. Calculate the molarity of the Pb(NO,),(aq) solution. concentration: M

Expert Solution
Step 1
Balanced reaction of Pb(NO3)2 with NaCl
Pb(NO3)2(aq) + 2NaCl(aq) ....> PbCl2(s) + 2NaNO3(aq)
Mass of PbCl2 obtained = 15.67 g
Molar mass of PbCl2 = 278g/mol
Moles of PbCl2 = 15.67g÷278g/mol
= 0.05637mol
