Question

After a precipitation reaction with 0.64 M H2SO4 was completed, you centrifuge the sample, dry and weigh it. The precipitate is found to weigh 0.109 grams. Based on this mass, what was the original concentration of the unknown Pb(NO3)2 solution in mol/L? Answer to 3 significant figures. [Pb(NO3)2] =
