    Option C. 0.34 moles

    Explanation:

    Data obtained from the question include:

    Molarity = 0.15M

    Volume = 2.25L

    Mole =

    Molarity = mole / Volume

    Mole = Molarity x Volume

    Mole = 0.15 x 2.25

    Mole = 0.34mole

    The number of mole of AlCl3 present in the solution is 0.34mole.
