  1. 12 mL x 0.4M AgNO3 = 4.8 millimols.
    8 mL x 0.8M NaCl = 6.4 mmols.
    AgNO3 + NaCl => AgCl + NaNO3
    This is a limiting reagent problem since amounts are given for BOTH reactants. You can tell, since the reactants and products are 1:1:1:1 that AgNO3 is the limiting reagent so you will produce 4.8 mmillimols (0.0048 mols) AgCl and convert that to grams. g = mols x molar mass.
