The new pressure of the gas would be 994 mmHg
Gas law
According to Charle's law, the pressure of a gas at a constant temperature varies inversely with its volume.
Mathematically: p1v1 = p2v2, where p1 and p2 = initial and final pressure, and v1 and v2 = initial and final volume.
In this case, v1 = 14.5 L, p1 = 720 mmHg, and v2 = 10.5 L
p2 = p1v1/v2 = 720 x 14.5/10.5 = 994 mmHg
