Answer:
The answer is: g / cm3.
Explanation:
Specific gravity is a comparison of the density of a substance with the density of water.
The specific gravity of water at a standard temperature and pressure is considered as one, so if the specific gravity of a substance is five, it means that it is five times denser than water.
It is common that said substance is always water, since it is known that it has 1 gram per milliliter or 1 gram per cubic centimeter.
The answer is: g / cm3.
