Density = 0.074 g / cm³. Density of water = 1 g / cm³. Specific gravity of water = density of football / density of water. Specific gravity of water = 0.074 / 1. Specific gravity = 0.074. The specific gravity of water is 0.074 and since it is less than that of water, the football will float on water. Example 4.

The specific gravity of a substance is the ratio of its density to a specified reference substance. This ratio is a pure number, containing no units. If the specific gravity ratio for a given substance is less than 1, that means the material will float in the reference substance. When the specific gravity ratio for a given material is greater ...

Density is defined as mass per unit volume. It has the SI unit kg m -3 or kg/m 3 and is an absolute quantity. Specific gravity is the ratio of a material's density with that of water at 4 °C (where it is most dense and is taken to have the value 999.974 kg m -3 ). It is therefore a relative quantity with no units. The words 'taken to have ...
