1) At 0Â°C and 1atm pressure the densities of air, oxygen and nitrogen are 1.293, 1.429 and 1.251 kg/m³. Calculate the percentage of nitrogen in air, assuming these two gases to be present only.
(it seems an easy one but still i m unable to do)

Use additivity of gases cocept.
The volume of air is equal to the volume of N2 + volume of O2.
write them in terms of mass and density. Also, mass of the air is equal to the sum of masses of nitrogen and oxygen.
