    Mass of sucrose = 81 g

    Explanation:

    Given dа ta:

    Mass of solute = ?

    Mass of water = 540 g

    % of solution = 15.0%

    Solution:

    Formula:

    % age of solution = mass of sucrose / mass of water * 100

    Now we will put the values.

    15 = mass of sucrose / 540 g * 100

    15 / 100 = mass of sucrose / 540 g

    0.15 = mass of sucrose / 540 g

    Mass of sucrose = 0.15 * 540 g

    Mass of sucrose = 81 g
