    0.74M

    Explanation:

    Step 1:

    Data obtained from the question.

    Initial concentration (C1) = 3M

    Initial volume (V2) = 185mL

    Final volume (V2) = 750mL

    Final concentration (C2) = ... ?

    Step 2:

    Determination of the new concentration of the solution.

    The new concentration of the solution can be obtained by using the dilution formula as shown below:

    C1V1 = C2V2

    3 x 185 = C2 x 750

    Divide both side by 750

    C2 = 3 x 185 / 750

    C2 = 0.74M

    Therefore, the new concentration of the solution is 0.74M
