A possible reason this is incorrect is when you plugged your numbers into PV=nRT, you only had 1 mmHg while the problem reads 17.5 mmHg (2333.14 Pa). Also, you are to subtract this from the barometric pressure to get your actual pressure, not multiply (according to the link mei gave). I don't remember doing problems exactly like this, but it appears otherwise you have set it up correctly. The only other thing I can suggest is to double check your units on R. You didn't list them.

Start studying!  Get a tutor if you need help.  And don't be embarrassed by it, there's no shame in wanting to better yourself.

Do your own homework..\nIt's not that hard.. YOu serach these things on the net and can learn all about them yourself..\nThen you will know what you are talking about and you will also fee better as you will have achieved something on your own.
