Composition of Air

A sample of air consisting of N_(2) and O_(2) was heated to 2500 K until the equilibrium N_(2)(g)+O_(2)(g)hArr2NO(g) was established with an equlibrium constant, K_(c )=2.1xx10^(-3) . At equilibrium, the "mole"% of NO was 1.8 . Eatimate the initial composition of air in mole fraction of N_(2) and O_(2) .

If dry air is considered to have average molecular mass 28.84. What is the composition of dry Air?

If dry air is considered to have only nitrogen and oxygen and is found to have average molecular mass 28.84. what is the composition of dry Air ?

What is the % composition of nitrogen by weight in air ?

The masspercentage in composition of dry air at sea level contains contains approximately 75.5% of N_(2) . If the total atmosphere pressure is 1 atm then what will be the partial pressure of nitrogen? [Given : average molecular mass of air = 29 ]

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?
