Determine the percent by mass of water in hydrated calcium


A 1.803 g sample of gypsum, a hydrated salt of calcium sulfate, CaSo4, is heated in a crucible until a constant mass is reached which is having the mass of the anhydrous CaSO4 salt is 1.426g.

1. Determine the percent by mass of water in the hydrated calcium sulfate salt.

2. Determine the moles of water removed and the moles of anhydrous CaSO2 remaining in the crucible.

3. Determine the formula of the hydrated calcium sulfate; that is, explain the whole number mole ratio of calcium sulfate to water.
