### 9.13

why must you assume that there is 1 mole of N?

it tells us to assume ideal gas conditions, which means we assume 1 mol of gas.

This question was simply poorly worded, because ideal conditions for a gas does not imply the number of moles. If it were standard conditions, then typically the amount of gas would ideally be 1 mol. However, ideal conditions simply pertain to abiding the ideal gas law.

I agree that this question was poorly worded. However, aside from its flaw of failing to mention the number of moles, it is a relatively straight-forward, good question. It forces us to recall the properties of an ideal gas and standard conditions.

So for future reference if they do not specify number of moles and say assume ideal gas conditions this automatically means 1mol of substance?

I would assume so.
