Asolution 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 18.86 g pbcl2(s) is obtained from 200.0 ml of the original solution. calculate the molarity of the pb(no3)2(aq) solution.

Find the mass, in grams, of 5.00*10^23 molecules of f2
