How many grams of aluminum chloride are produced when 18 g of aluminum are reacted with an excess of hydrochloric acid?
2AL(s) + 6HCl(aq) ---> 2AlCl3(aq) + 3H2(g)
mols Al = grams/molar mass
Convert mols Al to mols AlCl3 using the coefficients in the balanced equation.
Convert mols AlCl3 to grams. g = mols x molar mass.
