Word equation

Required

Moles of Chlorine produced

Solution

We change the word equation into a chemical equation (with a formula)

Aluminum bromide reacts with chlorine gas to produce Aluminum chloride and bromide gas

2AlBr₃+3Cl₂⇒2AlCl₃+3Br₂

moles Cl₂ = 9

Maybe you mean, <em>how many moles of Bromine can we produce?</em>

From equation, mol ratio Cl₂ : Br₂ = 3 : 3, so mol Br₂=mol Cl₂=9 moles
