W3 - Density, Specific Gravity, Specific Volume

Specific Gravity is defined as what?

ratio of the mass of a substance to mass of an equal volume of a standard substance

• compares weights of equal volumes

Specific Volume is defined as what?

Ratio of volume of a liquid to the volume of an equal mass of water

• compares volumes of equal weight

What is the formula of specific gravity?

Mass of solute / Mass of equal volume of water

What is the formula of specific volume?

1/(specific gravity)

The Archimedes Principles is defined as what?

a solid immersed in liquid displaces an amount of liquid equal to its own volume AND suffers an apparent loss in weight equal to the weight of the displaced liquid

Which increases the density of an aqueous liquid?

A. Reverse Osmosis

B. Distillation

C. Dissolving a salt in water

D. Density is a constant value for any chemical and cannot be changed

C. Dissolving a salt in water

Specific Volume is also defined as the volume of the unit of weight, which is the reciprocal to what?

Density: SV = 1/Density

SG and what are numerically the same?

Density

• therefore, SV = 1/Density or SG x SV = 1
