State the volume of air remaining in the lungs after a normal breathing.

Tidal volume is that volume of air which is inhaled (and exhaled) in one breath by a human during quiet breathing. For a normal man this volume is close to 0.6 litre. 35% of oxygen (in terms of molecular count) gets converted into carbon – di – oxide in the exhaled air. Nearly 21% of the air that we breath in is oxygen. Assume that a man is breathing when the air is at STP and the moisture content of inhaled and exhaled air is same. Estimate the difference in mass of an inhaled breath and exhaled breath.
