    The solution contains 335.5 grams of KCl

    Explanation:

    Step 1: Data given

    Volume of the KCl solution = 3.00 L

    Molarity of the KCl solution = 1.50 M

    Molar mass of KCl = 74.55 g/mol

    Step 2: Calculate moles KCl

    Moles KCl = molarity KCl solution * volume KCl solution

    Moles KCl = 1.50 M * 3.00 L

    Moles KCl = 4.50 moles

    Step 3: Calculate mass of KCl

    Mass KCl = moles KCl * molar mass KCl

    Mass KCl = 4.50 moles * 74.55 g/mol

    Mass KCl = 335.5 grams

    The solution contains 335.5 grams of KCl
