Do ideal gases forms solutions even they don't have intermolecular forces? please explain.
Well, I assume so.....
...now the air we breathe is a solution of dinitrogen, and dioxygen, and a few other gases, and at room temperature and pressure the behaviour is close to ideal.
And we recall Dalton's law of partial pressures, the which states that in a gaseous mixture, the pressure exerted by an component gas is PRECISELY the same PRESSURE it would exert if it alone occupied the container.
