Question

At 27 degrees and 760 torr pressure,N2O4(g) is 20% dissociated into NO2(g). The density of equilibrium gaseous mixture of these gases at 27 degrees and 760 torr pressure in g/L is

Answer 1

Is the answer 3.1 kg/m³ ?

Answer 2

Yes

Answer 3

How??

Answer 4

You can calculate the densities of pure N2O4 and pure NO2 at 1 atm and 300 K.

Then use the dissociation percentage given to work out the relative abundance of N2O4 and NO2 in the mixture.

Finally, combine the percentages and the densities above to find the density of the mixture.
