If 10.00 moles of aluminum chloride are decomposed into aluminum and chlorine gas, how many grams of chlorine gas are produced?

Question

531.8 grams Cl2

1,064 grams Cl2

1,595 grams Cl2

2,127 grams Cl2

Answer 1

First you need the balanced equation:

2 AlCl₃ → 2 Al + 3 Cl₂

(70.90 g Cl₂/1 mol Cl₂) (3 mol Cl₂/2 mol AlCl₃) (10.00 mol AlCl₃) = 1064 g Cl₂
