    b. 15 % (m / v)

    Explanation:

    The percent concentration (m / v) =

    mass of the solute / volume of the solution * 100

    From the question, the mass of glucose = 10.00 g

    The total volume of the solution = 66.67 mL

    using the above formula, and putting the respective values, the percent concentration (m / v) is calculated as -

    The percent concentration (m / v) = 10.00 g / 66.67 mL * 100 = 15 (m/v) %
