Could you plz help me out with this? What would be the weight of 1 litre of a 1 Molar solution of Cu2Cl2?Cu2Cl2 is a dimer of CuCl right and some of it should dissociate to give the same right? so will it be equal to that of a)molecular weight of Cu2Cl2? b)Molecular weight of CuCl? c)or do we have to find the equilibrium conc of CuCl and Cu2Cl2 in the solution and take the average molecular weight?
