Use C1V1 = C2V2 to calculate the molarity of a potassium bromide solution that is prepared by adding 125mL mL of water to 25mL mL of aqueous 2.00 M potassium bromide solution. Assume volumes are additive, and report your answer to three significant figures.

    Answer: 0.4M

    Explanation:

    This would be much easier if we first analized what was given from the question. This is illustrated below:

    C1 = 2M

    V1 = 25mL

    C2 = ?

    V2 = 125mL

    C1V1 = C2V2

    2x25 = C2 x 125

    Divide both side by 125, we have:

    C2 = (2x25) / 125

    C2 = 0.4M

    Therefore, the molarity of potassium bromide formed will be 0.4M
