I appreciate your description but I didn't want a difference between the two compounds.
I want to know the technical meaning of the '5' (what does it do?)
Does it make H >> 5H ?
Or does it make H20 >> 5H20 ?
It basically means 5 moles of H2O, given that one H2O is 1 mol
So instead of having 1 piece of H2O, you have 5 pieces of H2O?
Say, you have 1 apple, then you suddenly get the quantity of 5 times the amount of apples.
And lets say Apples Formula is ABC
Then for every component in A B C, there would also be 5 times amount in it as well.
Its just a measure of ratio.
PS: And When your calculating between the Copper Sulphate and Water, you'd compare the ratio between Copper Sulphate and Water
So CuSO4 has an invisible one in front of it.
And there is 5x of H2O
So take CuSO4 as Oranges
And H2O as Apples
You'd have 5x the amount of Apples than Oranges as the ratio is 1 : 5
Quite basic, but it'll get harder, and you shouldn't expand the 5 into H2O as taiga said below, you'll get a different chemical formula. quite different from that of H2O. IT JUST MEANS THERES 5x THE AMOUNT OF pieces in WHATEVER THAT IS.
Eg, you can't have 5 times expanded into Apples, it doesn't make anything.
