Question

what do you mean by observed molecular weight and theoretical molecular weight

Answer 1

theoretical molecular weight
it represents molecular weight of substance which is taken from dissociation and Association. it is also considered as normal molecular weight are calculated molecular weight

observed molecular weight
it represents the molecular weight of equilibrium mixture. It is also considered as abnormal molecular weight for experimental molecular weight of average molecular weight
