Solution Stoichiometry

Q. If a solution, made from 0.8 g of water and enough NaCl to yield a freezing point of -2.5, was added to excess lead (ll) nitrate solution, how many grams of precipitate would be expected? Please help me untangle this problem. I can see I need to determine the chemical equation, but the concentration of reactions (or colligative properties) and stoichiometry to find the limiting reactant is still abstract. Could you please help me work this out in a dimensional analysis format with canceling?

Solution Stoichiometry

Q. Luis went camping and found a bag with 2500 silverish looking metal cubes in a cavern in the hills of Yosemite. These cubes have a height of 10 cm. He believes it is either silver, aluminium, or nickel. Remembering you were a chemistry genius, Luis promises to give you 500 cubes of the metal if you can tell him what the metal it is. Using 250 mL of each following solution at the stated concentrations. You have to use your cubes to identify after all the reactions determine how many grams of solid metal will be left.
