The density of a substance is the ratio of its mass to its volume. the formula for density is: d = mass/volume. if the density and the volume of a liquid are known, its mass can be found by a) adding its density to its volume. b) dividing its density by its volume. c) multiplying its volume and density. d) subtracting its density from its volume

C) multiplying its volume and density

Explanation:

density = mass / volume

D = M / V

Multiply both sides by volume:

DV = M

Mass is equal to density times volume.

C) multiplying its volume and density.

Explanation:

The density of a substance is the ratio of its mass to its volume. The formula for density is: Density = mass/volume. If the density and the volume of a liquid are known, its mass can be found by multiplying its volume and density.

We know that:

Density = m/volume

Now you must, multiply both sides by volume:

Density  Volume = M
