The vapour density of a mixture containing NO2 and N2O4 is 38.3 at 27

1.	The vapour density of a mixture containing NO2 and N2O4 is 38.3 at 27°C. Calculate the mole of NO2 in 100 mole mixture.
Answer» Mol. wt. of mixture.of NO₂ and N₂O₄ = 38.3 x 2 = 76.6 Let a mole of NO₂ be present in 100 mole mixture wt. of NO₂ + wt. of N₂ O₄ = wt. of mixture, a x 46 + (100 - a ) x 92= 100 x 76.6 a = 33.48 mole

The vapour density of a mixture containing NO2 and N2O4 is 38.3 at 27°C. Calculate the mole of NO2 in 100 mole mixture.

Answer»

Mol. wt. of mixture.of NO₂ and N₂O₄ = 38.3 x 2 = 76.6

Let a mole of NO₂ be present in 100 mole mixture

wt. of NO₂ + wt. of N₂ O₄ = wt. of mixture,

a x 46 + (100 - a ) x 92= 100 x 76.6

a = 33.48 mole
