THE MASS OF AN EMPTY DENSITY BOTTLE IS 20g
THE MASS OF THE BOTTLE FILLED WITH WATER IS 50g
THE MASS OF THE BOTTLE FILLED WITH OIL IS 45g
IF THE DENSITY OF WATER IS 1g / cm3 , DETERMINE THE RELATIVE DENSITY OF THE OIL.
HENCE DETERMINE ITS DENSITY.
Relative density of the oil = (45g - 20g) / (50g - 20g) = 0.75
Density of the oil = 0.75 x 1g/cm3 = 0.75g/cm3
