    0.193 M to the nearest thousandth.

    Explanation:

    Molar mass of copper (ii) chloride

    = 63.546 + 2 * 35.45

    = 134.446 g.

    So in 2.60L of 1 M solution there is 134.446 * 2.6

    = 349.56 g of copper chloride.

    So the molarity of our solution is 67.3 / 349.56

    = 0.193 M.
