The problem can be solved using Boyle's Law, which states that P1V1 = P2V2, assuming the temperature and the amount of gas remain constant. First, convert the final pressure to the same units as the initial pressure (1 atm = 760 mmHg), so 1240 mmHg = 1240 mmHg / 760 mmHg/atm = 1.63 atm. Then, solve for V2: V2 = P1V1 / P2 = (1.50 atm * 5.0 L) / 1.63 atm = 4.6 L.
