Chemistry Stoichiometry Mass to Mass Calculations

Question

If 33.0 grams of aluminum reacts with an excess of copper (II) chloride, what amount of pure 

   copper will be produced?

Balanced Equation: 2Al+3CuCl2*2AlCl3+3Cu

 

Answer 1

2Al(s) + 3CuCl₂(aq) ==> 2AlCl₃(aq) + 3Cu(s)

Use dimensional analysis to solve for g Cu:

33.0 g Al x 1 mol Al/27.0 g x 3 mol Cu / 2 mol Al x 63.5 g Cu/mol Cu = 116 g Cu
