Question

Relationship between apparent specific gravity and specific gravity

Answer 1

Density = Mass / Volume. Specific gravity is the density of a substance divided by the density of water. Since water has a density of 1 gram/cm³ (at sea level, and 4°C) specific gravity is usually very close to the same value as density

Answer 2

True specific gravity can be expressed mathematically as: where is the density of the sample and is the density of water. The apparent specific gravity is simply the ratio of the weights of equal volumes of sample and water in air: where represents the weight of sample and the weight of water, both measured in air.
