`PV = (w)/(m)RT` or `P = (w)/(V.m) RT` or `P =(d)/(m) RT,` at sea
level atmospheric pressure is high thus d is high

Air at sea level is dense. This is a practical application of

Assertion : At higher peaks of mountains, people suffer from high altitude sickness (sluggish feeling, breathlessness etc.) due to lesser oxygen intake at each breather Reason : Air at sea level is dense because it is compressed by the mass of the air above it. The atmospheric pressure at higher peaks of mountains is lower causing the air at those heights to be much less dense than at sea level.

At sea level, the composition of dry air is approximately N_(2)=75.5% , O_(2)=23.2% , and Ar=1.3% by mass. If the total pressure at sea level is 1 "bar" , what is the partial pressure of each component?

At sea level, atmospheric pressure is
