the volume of fluid with the same mass as the hydrometer
... is 90% of the volume of the hydrometer
density = mass / volume
... for the hydrometer ... m / v = 0.80 g/cm^3
... for the fluid ... m / (.9 v) = (m / v) / .9 = (.80 / .9) g/cm^3
... is 90% of the volume of the hydrometer
density = mass / volume
... for the hydrometer ... m / v = 0.80 g/cm^3
... for the fluid ... m / (.9 v) = (m / v) / .9 = (.80 / .9) g/cm^3
