calculating density by the composition of air(% volume)

Suppose a chemcial reaction produced 2 moles of Nitrogen gas(N2), can we
calculate the density of Nitrogen(N2) produced by using these two data?

1)there is 78%(% by volume) of Nitrogen(N2) in air
2)the molar volume in RT is 24 dm3

Please tell me the steps of calculating the density in this situation....
