The variation in the atmospheric pressure with height can be estimated by balancing force due to gradient in pressure with the gravity. Assume ideal gas behaviour, isothermal conditions with temperature T=290 ~K , and constant composition of air throughout the atmosphere. The approximate percentage reduction in oxygen at a height of 1 km above sea level is (note: take the mean molecular mass of air at the sea level a
