A closed container with a volume of $2000\,\text{cm}^3$ contains air at high pressure. The container is placed on a top-pan balance. The balance shows $200.00\,\text{g}$. A vacuum pump removes all the air, and the balance reading then falls to $196.00\,\text{g}$. What is the density of the pressurised air?
- A$0.00200\,\text{g cm}^{-3}$
- B$0.098\,\text{g cm}^{-3}$
- C$4.00\,\text{g cm}^{-3}$
- D$10.2\,\text{g cm}^{-3}$
