Front

If a substance has a volume of 5 cm³ and a mass of 52.5g, what is its density?

Back

Density = Mass/Volume = 52.5g/5cm³ = 10.5 g/cm³.

Front

Define density.

Back

Density is the mass of an object divided by its volume.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.
