A certain mass of the oxygen gas occupies 7 L volume under a pressure of 380 mm Hg. The volume of the same mass of the gas at standard pressure, with temperature remaining constant, shall be (UP CPMT 2009)

Boyle's law relates the volume and the pressure of a given mass of a gas at constant temperature. According to Boyle's law, At constant temperature, 1 1 2 2 pV p V 380 × 7 = 760 × V2 2 380 7 3.5 760 V L x
