someone anwer please i have an exam help me noe how to calculate it

anonymous · Answer

If you work out how many moles of water there are in 1g first, then that would be 1/17 or 0.0588 moles. 1 mole takes up 22.4litres at standard temperature and pressure so you can calculate how much volume the fraction takes up by dividing 22.4 by 17. Next figure out how much more volume the molecules take up when the temperature is increased to 323oC. You need to use Charles' Law where the volume over the temperature (in Kelvin) is a constant. Standard temp is 298K whereas 323oC is 500K so the volume will be proportionally bigger.

so wut is the final answer??

I'm afraid I don't generally give out answers - that would allow people to find out answers without understanding what they are doing. There should be enough in my first reply to allow you to calculate - have a go and I'll see if you're right or not. Best wishes,
