Which will have greater volume when the following gases are compared at S.T.P. (a) 1.2 l N 2 at 25°C and 748 mm Hg (b) 1.25 l O 2 at S.T.P.?

(a) 1.2 l N 2 at 25°C and 748 mm Hg Initial conditions : P 1 = Initial pressure of the gas = 748 mm Hg V 1 = Initial volume of the gas = 1.2 l T 1 = Initial temperature of the gas = 25°C = 25 + 273 = 298 K Final conditions : P 2 (Final pressure) = 760 mm of Hg T 2 (Final temperature) = 273 K V 2 (Final volume) = ? By Gas Law: Substituting the values : ∴ Volume of N 2 at S.T.P. = 1.081 l and volume of O 2 at S.T.P. is 1.25 l . Hence, volume of O 2 at S.T.P. is greater than N 2 at S.T.P.
