    For 1 moles Aluminium we need 3.0 / 2 = 1.5 moles Chlorine gas (Cl2)

    Option C is correct

    Explanation:

    Step 1: data given

    Aluminium = Al (s)

    Chlorine gas = Cl2 (g)

    Step 2: The balanced equation

    2 Al (s) + 3 Cl2 (g) → 2 AlCl3 (s)

    Step 3: Calculate moles Cl2

    For 2 moles Aluminium we need 3 moles chlorine gas to react, to product 2 moles AlCl3

    For 1 moles Aluminium we need 3.0 / 2 = 1.5 moles Chlorine gas (Cl2)

    Option C is correct
