Question

Which equation is used to determine the density of a substance? D = M/V D = M X V D = V/M D = MV2

Answer 1

The equation to determine the density of a substance is D=M/V

Answer 2

Right answer:
`D=(M)/(V)`

Every substance, body or material has mass and volume, however the mass of different substances, bodies or materials occupy different volumes.

This is where density appears as a physical characteristic property of matter that establishes a relationship between the mass of a body or substance and the volume it occupies.

In formal words:

Density
`D` is defined as the relationship between the mass
`M` and volume
`V` of a specific substance or material and is expressed in the following equation:

`D=(M)/(V)`

The density is a scalar quantity and according to the International System of Units its unit is
`D=(kg)/(m^(3))`

It should be noted that the density of a body is related to its buoyancy, a substance or body will float on another fluid if its density is lower.
