A gas is bubbled through water at a temperature of 30°C and at an atmospheric pressure of

100.2 kPa. What is the pressure of the dry gas?

2 answers

Ptotal = pH2O + pgas
Ptotal = 100.2 kpa
pH2O--look up vapor pressure H2O at 30 C (in kPa or convert to kPa or convert 100.2 kPa to mm Hg and use pH2O in mm Hg)
Substitute and solve for pgas.
ur wrong its 92
