How many molecules of water of crystallisation are present in one molecules of copper sulphate?
Answers
How many of the molecules in 1 mole are present in compounds having water of crystallization attached to them?
Since I'm only a highschool student, I may be wrong. From what I understand of your question, you're asking how many molecules in one mole of a compound's hydrated crystal have water molecules associated with them? If you look at the formula of the hydrated crystal, you'll find that the number of water molecules denotes that on average, most of the molecules of the compound have <X> molecules of water attached to it. So in a hydrated crystal, nearly all the molecules will have a certain number of water molecules associated with them. So say you have a crystal of copper sulphate, which commonly occurs as a pentahydrate. So, one molecule of copper sulphate in the lattice has 5 molecules of water associated with it. This is true for nearly all of the molecules. To summarize, most of the crystal's molecules have water with them, on average. Hence in one mole, you'll have on average 6.023 x 10^23 molecules with water. Feel free to correct me!
