    Oh, one thing that has been bothering the heck out of me, the question about the balloon?
    'Show that it's volume at take-off is so-and-so:'

    How did everyone approach that? Surely you needed to know the amount of moles, which was not given?

    didn't have a clue when it came to this paper, and I did a load of past paper revision for it too. Oh well I suppose at the end of the day it's down to the luck of the draw.
