If 53.62 ml of an oil weighs 48.34 g what is the specific gravity of the oil

The specific gravity is the ratio of the density of oil to the density of water. Since the density of water is 1g/ml, the density of a substance is numerically the same as the specific gravity.

However, specific gravity is a dimensionless number, while density has units mass/volume.

So, the density of oil is .901 g/ml, but the specific gravity is just .901

In Imperial units, the density of the oil is 56.2 lb/ft^3, but the specific gravity is still .901
