A student enters in a Physics lab wants to know the atmospheric pressure, how he can measure it? Through certain device he founds that its value is 1.083 bar, if some amount of oxygen gas is introduced in the space above the Mercury level, due to which this level falls by 5 cm. Predict the volume of oxygen gas introduced above the Mercury level, if it is assumed that its height in a tube is 1 m with 2 cm2 area of cross section.
