In the balanced double replacement reaction of calcium chloride CaCl2 and aluminum sulfate Al2(SO4)3, how many grams of calcium sulfate can be produced if you start the reaction with 18.97 grams of calcium chloride and the reaction goes to completion?
3CaCl2 + Al2(SO4)3 ==> 3CaSO4 + 2AlCl3
mols CaCl2 = grams/molar mass
Convert mols CaCl2 to mols CaSO4 using the coefficients in the balanced equation.
Convert mols CaSO4 to g. g = mols x molar mass.
the final answer is 7750.80/333.012= 23.27g CaSOa if you follow DrBob222 steps
