Calculate these volumes. (a) what is the volume of 11.3 g graphite, density = 2.25 g/cm3?

D=m/v

v=m/d

v=11.3/2.5

v=4.52cm cubed

The volume is 5.02cm³.

Explanation:

The formula of density is: density (d) = mass (m) / volume (v)

So, to calculate the volume from density and mass we use the density formula by making a few math steps:

- From this: d = m/v

- The volume pass to the other side of the formula as the density goes dividing the mass: v = m/d

- Then, replace the information: v = 11.3g / (2.25g/cm³)

- By dividing, we find that the volume is v = 5.02cm³
