Homework Statement


Calculate the empirical formula of each hydrate


Homework Equations



Mass of MnSO4 x XH2O...
-Hydrate = 1.8g
-Anhydrous salt = 1.59g
-Water = .21g


The Attempt at a Solution



I thought you would set 1.8g MnSO4*XH2O((Molecular mass of MnSO4)/(Molecular mass of MnSO4*XH2O)), but im not sure what to do.

You have to find the molar ratio between anhydrous salt and water.
