12.3g of iron(ii)tetraoxosulphate(vi)crystals when heated gave 6g of the anhydrous salts.if only its water of crystalisation is lost as a result of the heating,calculate the % by mass of the water of crystalization.

Note: The weird name you have used for FeSO4 is not an IUPAC approved name.
12.3 g = mass FeSO4 + H2O
-06.0 g = mass FeSO4
--------------------
6.3 g = mass water of crystallization.
%H2O = (mass H2O/mass sample)*100 = ?
