    Please help me calculate the molality of a solution that contains 51.2 g of C10H8 in 500 ml of carbon tetrachloride. The density of CCl4 is 1.60 g/ml.
    I also need help calculating the molarity of a solution that contains 9.0 g of (COOH)2 in 1500 ml of solution.

    Solution Preview

    Molality is defined as: (moles of solute) / (Kg Solvent)

    In this case: (moles C10H8) / (Kg carbon tetrachloride)

    M.W. of C10H8 = 128 ...
