What is C.G.S. unit of density?

• A. g cm⁻³
• B. g m⁻³
• C. g cm⁻²
• D. kg m⁻³

The C.G.S. unit of density is defined as mass per unit volume. In the C.G.S. system, the appropriate unit for density is grams per cubic centimeter.

Correct Answer

The correct answer is A. g cm⁻³.

Understanding Density

Density is a measure of how much mass is contained in a given volume. It helps in identifying substances and understanding their properties.

Units Explained

• g cm⁻³: Grams per cubic centimeter, the C.G.S. unit of density.
• g m⁻³: Grams per cubic meter, a unit used in the M.K.S. system.
• g cm⁻²: This unit is not applicable for density.
• kg m⁻³: Kilograms per cubic meter, another unit used in the M.K.S. system.

In summary, when dealing with density in the C.G.S. system, remember that it is measured in grams per cubic centimeter.
