Air is trapped in a cylinder by a piston. The piston is moved inwards so that the volume of the air reduces. [diagram of cylinder with piston, air with initial volume and air with final volume] The density of the air in the syringe at the initial volume is 0.0012 g / cm3. What is the density of the air in the syringe at the final volume?

1. A0.0006 g / cm3
2. B0.0012 g / cm3
3. C0.0024 g / cm3
4. D0.0048 g / cm3
