Tbis is a limiting reagent (LR) problem.
Pb(NO3)2 + 2NaCl ==> PCl2 + 2NaNO3
mols Pb(NO3)2 = M x L = ?
mols NaCl = M x L = ?
Using the coefficients in the balanced equation, convert mols Pb(NO3)2 to mols PbCl2.
Do the same and convert mols NaCl to mols PbCl2.
It is likely that the two numbers will not agree which means one of them is wrong; the correct value in LR problem is ALWAYS the smaller value and the reagent responsible for that number is the LR.
Using the smaller value, convert mols NaCl to g. g = mols x molar mass.
