Question

If 22.5 L of nitrogen at 748 mm Hg are compressed to 725 mm Hg at constant temperature, what is the new volume?

Answer 1

The new volume `=23.2 L`

Explanation:

We use Boyle's Law

`P_1V_1=P_2V_2`

`P_1=748 mm Hg`

`V_1=22.5 L`

`P_2=725 mm Hg`

`V_2=(P_1V_1)/P_2`

`=(748*22.5)/725=23.2 L`
