    Mass of the solution = 54.75 g

    Explanation:

    Mass of solid dissolved = 4.75 g

    Mass of the solution = Mass of solid dissolved + Mass of water.

    Mass of water = Volume x Density

    Volume = 50 mL = 50 cm³

    Density = 1 g/cm³

    Mass of water = 50 x 1 = 50 g

    Mass of the solution = 4.75 + 50 = 54.75 g
