Osmium has a density of 22.6 g/cm^3. What volume (in cm^3) would be occupied by a 21.8 g sample of osmium?
Snowcat [4.5K]

0.9645 cm³ is the occupied volume by a 21.8 g sample of osmium of density of 22.6 g/cm^3.

Given values are:

  • Mass, m = 21.8 g
  • Density, d = 22.6 g

Density is given by,

  density = \frac{mass}{volume}

⇒volume = \frac{mass}{volume}

⇒volume = \frac{21.8}{22.6}

⇒volume = 0.9645 cm^3

∴The volume is 0.9645cm^3
