The possible molecular mass of MgSO4 in its dilute solution can be

MgSO4 is an electrolyte in dilute solution it undergoes dissociation,accordingly molar mass changes. The range of molar mass isNormal molar massi to Normal molar mass (i = Vant Hoff factor)Molar mass is in between 60 and 120 for different degree of ionization in dilute solution
