Acrystalline salt when heated becomes anhydrous and loses 51.2 % of its weight.The anhydrous salt on analysis gave the following percentage composition Mg = 20.0% , S = 26.6 % , O = 53.33 % Calculate the molecular formula of the anhydrous salt and the crystalline salt. Molecular weight of the anhydrous salt is 120.
