5. ### This is a picture of my book in here the volume of one mole is written as 1L while the volume of one mole of a molecule is 22.4L why ?

The volume of 1 mole of a gas is 22.4L at standard temperature and pressure , 1 atmosphere and 0C. If you increase the pressure inside the balloons to 22.4 atm , then you can have 1 mole in 1L. I don't think may balloons would stand that kind of pressure ...
