Front

What is the formula for density?

Back

Density = mass / volume.

Front

How do you calculate the density of an object?

Back

Density is calculated by dividing the mass of the object by its volume.

Front

What is the density of an object with a mass of 27 g and a volume of 3 mL?

Back

Density = 27 g / 3 mL = 9 g/mL.

Front

What happens to the density of an object if its mass increases while its volume remains constant?

Back

The density increases.

Front

What happens to the density of an object if its volume increases while its mass remains constant?

Back

The density decreases.
