    0.770 M means 0.770 mole of copper I nitrate is dissolved in one liter of the solution.

    Mass of one mole = 63.5 + 14 + 3 * 16 = 125.5 grams

    Mass = 0.770 * 125.5 = 96.635 grams

    This is the mass of CuNO3 in one liter of the solution. Let’s use a proportion to solve this problem.

    V ÷ 6.53 = 1000 ÷ 96.635

    V = 6,530 ÷ 96.635

    This is approximately 65 ml of water.
