Volume of oxygen in air is approximately _____ of the volume of air.
What is the total volume (approximately) of air that can be forcefully exhaled after a normal inspiration?
The air is a mixture of a number of gases. The major components are oxygen
and nitrogen with approximate proportion of 20% is to 79% by volume at 298
K. The water is in equilibrium with air at a pressure of 10 atm. At 298 Kif the
Henry’s law constants for oxygen and nitrogen are 3.30 × 107 mm and 6.51 × 107 mm respectively, calculate the composition of these gases in water.
