The vapour density of a sample of N2O4 gas is 35. What per cent of N2O4 molecules are dissociated inNO2?
molar mass = 2 * Vapour Density
The Attempt at a Solution
I tried to solve this question this way,
Let the initial number of moles of N2O4=a
and, assume that the degree of dissociation is α
So,the reaction would be
N2O4 ---------> 2NO2
a ---------------0 (Before Dissociation)
And also since VD of N2O4 gas is 35. So,the mass of N2O4 gas would be=35*2=70.
But i do not know what i shall do next?
I will be thankful for any help!
