The crust is the thinnest layer of the earth accounting for only 1% total volume of the planets.
Compositionally, the earth is divided into three layers which are the crust, mantle and the core.
- The crust is the outermost layer of the earth. It rich in silicate minerals. The rocks are classified into igneous, sedimentary and metamorphic rocks.
- The mantle takes up about 84% of the total volume of the earth. It is located in between the crust and the core. It is predominantly made up of ferro-magnesian silicate minerals.

Answer: V = 16.1 L
Explanation:Using Ideal gas law formula PV = nRT, we will derive for Volume. V = nRT / P
V = 0.34 mole ( 0.0820574 L.atm/ mole .K)(321 K ) / 0.5567 atm
= 16.1 L
