to figure out the pressure of the dry gas, use this equation:
Pgas= Ptotal - Pwatervapor ...(P means pressure) you need to find a
conversion chart of 4 degrees celsius (*into mm Hg*/torr/atm)

4 degrees celsius = 0.81359 kPa ... convert to mm Hg by dividing by
101.325, then multiply by 760.0. 4 degrees celsius = 6.10mm Hg now
plug into the problem above... Pgas= 750mm Hg - 6.10mm Hg =
**743.9 mm Hg of dry oxygen gas** ...that should be the correct
answer, check with a chem teacher or something. ...I myself am
trying to figure out how to solve the volume of dry gas at STP
later to figure out the pressure of the dry gas, use this equation:
