WebI identified the solution as KI, but then when it comes to finding the molarity, I have no idea how. I reacted the KI with Pb(NO3)2 and then AgNO3 in test tubes and put the solutions through filters to get the precipitate only. I now have the mass of the precipitate, but I don't know what to do with that information. Web1) Assume 100.0 g of the solution is present. H2SO4---> (100.0 g) (0.9600) = 96.00 g H2O ---> (100.0 g) (0.0400) = 4.00 g 2) Determine the mole fraction: H2SO4---> 96.00 g / 98.078 g/mol = 0.978813 mol H2O ---> 4.00 g / 18.015 g/mol = 0.222037 mol 0.978813 mol + 0.222037 mol = 1.20085 mol H2SO4---> 0.978813 mol / 1.20085 mol = 0.8151

WebQuestion: Someone needed to determine the molarity of HCl in a solution but couldn’t use titration because there was an additional acid in the solution.
