Question

A mixture of nitrogen and hydrogen. In the ratio of one mole of nitrogen to three moles of hydrogen, was partially converted into nh3 so that the final product was a mixture of all these three gases. The mixture was to have a density of 0.497 g per litre at 25c and 1.00 atm. What would be the mass of gas in 22.4 liters at 1atm and 273 k ? Calculate the % composition of this gaseous mixture by volume.

Answer 1

Explanation:

Correct option is

A

11.33 g

PM=ρRT

Thus, ρ∝

T

1

ρ

′

=ρ×

T

′

T

=0.46×

273

300

=0.505g/L

The mass of gas in 22.4 L will be 22.4×0.505=11.33g
