Question

If a substance has a density of 2.7g/cm3 and a mass of 86.4g, what is its volume?

Answer 1

32cm³

Step-by-step explanation:

Given parameters:

Density of substance = 2.7g/cm³

Mass of substance = 86.4g

Unknown:

Volume of substance = ?

Solution:

Density is the mass per unit volume of a substance.

Density =
`(mass)/(volume)`

Since the unknown is volume we solve for it;

mass = density x volume

86.4 = 2.7 x volume

volume =
`(86.4)/(2.7)` = 32cm³
