CHEM HELP??? 3.10-g mixture of lead nitrate and potassium nitrate are mixed with an excess solution of sodium chloride. There is a precipitate with a mass of 1.10 grams. Calculate the mass percent of the lead nitrate in the solution (remember the amount the lead nitrate solution is given in mass not in L). Show factor label for stoichiometry. First write the net ionic equation.
