2- What is the specific gravity of a substance with a density of 2,5 mathrm(~g) / mathrm(cm)^3 ?

The specific gravity of a substance is the ratio of its density to the density of water at 4°C (the temperature at which water has its maximum density). The density of water at 4°C is approximately .Given that the density of the substance is , the specific gravity can be calculated as follows: Therefore, the specific gravity of the substance with a density of is 2.5.
