According to Boyle's Law, which states that P1V1 = P2V2 for a given amount of gas at constant temperature, the volume is inversely proportional to the pressure. Here, P1 = 760 mmHg, V1 = 1.40 × 10^3 mL, P2 = 380 mmHg. Solving for V2 gives V2 = (P1V1)/P2 = (760 mmHg * 1.40 × 10^3 mL) / 380 mmHg = 2,800 mL.
