    Assuming that you’re looking for the concentration of water in the solution, then it would be 0.028 M.

    You would have to use the formula:
    c1v1 = c2v2, where c =concentration and
    v = volume

    C1 = ?
    V1 = 250 mL
    C2 = 0.2 M
    V2 = 35 mL

    C1 x 250 mL = 0.2 M x 35 mL

    C1 = (0.2 M x 35 mL) / 250 mL

    C1 = 0.028 M of water added to 35mL of 0.2M HCl

    Therefore, there is 0.028 M of water added to 35mL of 0.2M HCl
