< Question 39 of 41 The addition of 0.3800 L of 1.150M KCI to a solution containing Ag* and Pb?+ ions is just enough to precipitate all of the ions as AgCl and PbCL,. The total mass of the resulting precipitate is 62.10 g. Find the masses of PbCl, and AgCl in the precipitate. mass of PbCl,: mass of AgCl: A solution contains Al and Co. The addition of 0.3823 L of 1.654 M NAOH results in the complete precipitation of the ions as Al(OH), and Co(OH),. The total mass of the precipitate is 22.83 g. Find the masses of Al+ and Co+ in the solution. mass of Al3+. mass of Co+.
