Show that the potential height (energy required to separate 2 nitrogen molecules from each other) for N2 is ~ 0.01eV, given that latent heat of evaporation is 210 Jg^-1 and molecular weight is 28 for N2.

2. Relevant equations

I'm thinking that this equation might be of use:

Latent heat = potential height x 0.5 x N x n

N = number of atoms in sample

n = coordination number (number of nearest neighbors surrounding a given atom)

3. The attempt at a solution

28 / 6.02 x 10^23 = 4.65 x 10^-23 g per nitrogen atom

How should I progress from here? Using dimensional analysis, it appears that I might have to multiply (4.65 x 10^-23) by 210 .

Thanks x
