Answer 2

Water molecules in gypsum and plaster of Paris

Explanation:

• The salts which have specific amount of water molecules attached to them, are called as hydrated salts.
• Gypsum and plaster of Paris are considered as hydrated salts because both of the compound has some amount of water molecules attached to it.
• Gypsum is chemically called as calcium sulfate dihydrate and its molecular formula is $CaSO_4.2H_2O$. It is composed of two water molecules.
• On the other hand, Plaster of Paris is known as calcium sulfate hemihydrate and its formula is $CaSO_4.\frac{1}{2}H_2O$. It is composed of half molecule of water.
• Thus the difference of water molecules present in gypsum and Plaster of Paris is 1.5. (2-0.5).
