    Hello sorry dont ignore this post? so latent heat of evapouration of sodium chloride is needed

    relavant equations:
    Q = mL

    So I think i have the energy to break one bond, of na -cl, by considering couloumbs force and having the bond length 0.282nm

    so to get latent heat, would i multiply energy to break bonds by 6 for 6 bonds and then divide by mass of that one atom? but which one the sodium or the chlorine or the mass of all the atoms involved in the bonds?

    Thank you soo much would appriciate a reply soon this homework is in for tomorrow.
