0^{\circ}\text{C}

and 1.0 atm (

= 1.01 \times 10^5 \text{ N/m}^2

) pressure the densities of air, oxygen and nitrogen are

1.284 \text{ kg/m}^3

1.429 \text{ kg/m}^3

and

1.251 \text{ kg/m}^3

respectively. Calculate the percentage of nitrogen in the air from these data, assuming only these two gases to be present.
