You multiply the density by the volume.

Density ρ is defined as mass per unit volume.

#ρ = m/V#

You can rearrange this to get the expression for the mass.

#m = ρ×V#


If 500 mL of a liquid has a density of 1.11 g/mL, what mass of liquid is present?

#m = ρ×V = "500 mL" × "1.11 g"/"1 mL" = "555 g"#
