Explanation / Answer

Mass of hydrate = 2.02 g

Mass of anhydrate = 1.14 g

During heating water of hydration loses from the compound .

11)Mass of water of hydration = 2.02 - 1.14 = 0.88 g

12) % of water of hydration = (0.88 × 100)/2.02 = 43.56 %

13) Formula mass of anhydrate(CuSO4) = 159.61 g

14) Moles of anhydrate =mass of anhydrate / formula mass of hydrate = 1.14/159.61 =0.007 moles

15) Moles of water of hydration =mass of water of hydration / formula mass of water = 0.88/18 = 0.049 moles

16) Moles ratio of water of hydration to anhydrate = 0.049/0.007 = 7

17) Thus as per given data formula of hydrate is CuSO4 . 7H2O
