    (0.4734 dm^3)(0.5000 mol/dm^3) = ____moles Ag+
    Moles Cl- = moles Ag+
    Grams of Cl- = (35.453 g/mol)(moles Cl-)
    Grams of metal, M, = 1500g - grams Cl-
    From the grams of M and grams of Cl- find the % composition of the sample.
    Find the % composition of some chlorides: FeCl2, FeCl3, CuCl2, CaCl2, etc. until you find the one that matches the % composition of your sample.
