Why is the value of a substance’s specific gravity always the same numerically as its density?

Because it is always the substance’s density divided by the density of water which is 1 g/cm 3
Because it is always the substance’s density multiplied by the density of water which is 1 g/cm 3
Because specific gravity is the inverse of density
Because these represent the same measurement

Answer:

Because it is always the substance’s density divided by the density of water which is 1 g/cm 3

Explanation:

The density of water is 1g/cm³;

  Specific gravity = [tex]\frac{density of substance}{density of water}[/tex]

Since specific gravity is a relative comparison of a substance density with that of water, the values always the same.

Density of water is 1 and it will have no effect on the density of the substance.

The only difference is in the units. The density of a substance will have a unit but that of the specific gravity will have no unit.

Numerically, dividing by 1 has no implication.

Answer:  the answer is C

Explanation:Specific gravity is the density of a substance divided by the density of water. Since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density
