How many grams of bromine are required to react completely with 37.4 grams aluminum chloride?

  • Chemistry -

    Actually, the reaction you're proposing will not occur; however, here is how you work the problem.
    2AlCl3 + 3Br2 ==> 2AlBr3 + 3Cl2
    mols AlCl3 = grams/molar mass
    Convert mols AlCl3 to mols Br2 using the coefficients in the balanced equation.
    Convert mols Br2 to g. g = mols x molar mass.
