I have no idea where to begin with this. Can someone please help me work this out. I need to get this sorted asap. 
You are told that the Mr = 200 and you can see from the formula that there are 10 water molecules per formula unit.
Hence in 200g there are 10 moles of water.
So how many moles of water in 5g?
