    Option C. 0.23 molar

    Explanation:

    The following data were obtained from the question given:

    C1 = 0.5 M

    V1 = 340mL

    V2 = since 400mL was added to the original volume, therefore = 340 + 400 = 740mL

    C2 = ?

    The concentration of the diluted solution can be calculated by using the following:

    C1V1 = C2V2

    0.5 x 340 = C2 x 740

    Divide both side by 740

    C2 = (0.5 x 340) / 740

    C2 = 0.23M

    Therefore, the new concentration of the solution is 0.23M
