Question

Calculate the percentage of water of crystallisation in hydrated copper sulphate.cuso4.5h2o

Answer 1

W.K.T molar mass of Cuso4.5H2O = 159.609 + 90 = ~250. Mass of water of crystallization = 5 * 18 = 90. Percentage = 90/250 * 100= 36%.

Actually, it refers to the water that is found in the crystalline framework and includes metal complex or salt. This have been found directly bonded to the metal cation.

Answer 2

Answer:

64+32+64+10+80

250

90/250×100

36% answer
