    Mass of medicinal agent taken = 1.2 g

    the volume is 60 mL

    Specific gravity = 1.20

    So the mass of solution = specific gravity X volume = 1.20 * 60 = 72g

    Now if we have increased the volume by 0.2 so the new volume = 60.2

    New mass = 72 + 1.2 = 73.2

    Specific gravity = mass / volume = 73.2 / 60.2 = 1.22 g/mL
