Question

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

Answer 1

Answer:

32cm³

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  = $\frac{mass}{volume}$

Since the unknown is volume we solve for it;

   mass  = density x volume

   86.4 = 2.7 x volume

    volume  = $\frac{86.4}{2.7}$   = 32cm³
