the picture didn't work. it is U shaped with Hg in the middle and an open end. The distance between the Hg, under the open air portion is 18cm, which is before the bottom of the U. Does that make sense. Basically a manometer.

do I just change the 18cm's to 180mm to help work this out? Would it look something like this: Pressure gas = 180mmHg+0.95atm/760mmHg? 180.95mmHg/760mmHg = 0.238atm?? I think I am way off.
