Welcome to TSR Physics.

This question is done using the standard formula

Do you know this formula?

Just put in the values given in the question.
3. To add to Stonebridge's post above, the formula is derived by simply making a ratio using this equation:

The moles in either case is constant, R of course is the same in both, thus simply making a ratio:

Re-arrange to achieve the above.
4. Can you please work it out for me? Cos I dont get ir
