3. the mass of a crucible and a hydrated salt was found to be 21.447 g. the mass of the crucible and the
anhydrous salt was 20.070 g. the mass of the crucible was 17.985 g.
(1) calculate the mass of the hydrate heated.
(2) calculate the mass of water lost from the hydrate during heating.
(3) calculate the percent water in the hydrate.
