Specific gravity is a number representing the ratio of a mineral's weight to the weight of an equal volume of water. TRUE FALSE
777dan777 [17]

Answer: True

Explanation: Specific Gravity of a body, also called its Relative Density, is the ratio of the density of that body to the density of a reference material (usually water).

With the Mathematics done right, it is evident that the specific gravity of a body would be equal to the ratio of mass/weight of the body to the mass/weight of an equal volume of water.

S.G = (Density of body)/(Density of water)

Density of Body = (mass/weight of body)/(volume of body)

Density of water = (mass/weight of water)/(volume of water)

If volume of Body = Volume of water, then,

S.G = (Mass/Weight of body)/(Mass/Weight of equal volume of water)
