Air is enclosed in a cylinder by means of a piston. The piston is pushed inwards, causing the air volume to decrease. At the starting volume, the density of the air in the syringe is $0.0012\ \text{g cm}^{-3}$. What is the density of the air in the syringe at the final volume?
- A$0.0006\ \text{g cm}^{-3}$
- B$0.0012\ \text{g cm}^{-3}$
- C$0.0024\ \text{g cm}^{-3}$
- D$0.0048\ \text{g cm}^{-3}$
