If an object has mass of 30.0g and volume of 30.8cm3 calculate its density

Answer 1

Density is equal to mass divided by volume.

First, define our variables:

D = m/V

D = ?

m = 30.0 g

V = 30.8 cm³

Second, plug and chug:

D = m/V = (30.0 g)/ (30.8 cm³) = 0.974 g/cm³

The density of the object is 0.974 g/cm³.

Note: The density value has three significant figures because the mass and volume values also had three sig figs.
