The following data were collected from a gravimeter analysis of a hydrated salt;
Mass of crucible, lid and hydrated salt (g) 21.171
Mass of crucible and lid (g) 18.733
Mass of crucible, lid and anhydrous salt (g) 20.122
Calculate the percent water in the hydrated salt. Determine the percent by mass of water in copper (II) sulphate pentahydrate,CuSO4 . 5H2O? Explain what mass due to waters of crystallization is present in a 50.0 g sample of CuSO4 .H2O?
