Give the percentages of O_2 in atmospheric air and alveolar air.

What is the density of wet air with 75% relative humidity at 1 atm and 300 K? Given : vapour pressure of H_(2)O is 30 torr and average molar mass of air is 29 g mol^(_1) .

Differtiate between: Inspired air and alveolar air.

In the equilibrium 2SO_(2)(g)+O_(2)(g)hArr2SO_(3)(g) , the partial pressure of SO_(2),O_(2) and SO_(3) are 0.662,0.10 and 0.331 atm respectively . What should be the partial pressure of Oxygen so that the equilibrium concentrations of SO_(3) are equal ?
