A sample of methane gas, CH4, was collected over water at 25.0 ºC and 730. torr. The volume of the wet gas is 4.64 L. What will be the volume of the dry methane at standard pressure?

Answer 1

I see MANY posts. Is this a homework dump?
Ptotal = pH2O + pCH4
Ptotal = 730 torr
pH2O = look up vapor pressure H2O @ 25 C. If it isn't in torr (mm Hg) convert so that both pressures are in the same units.
Solve for pCH4 of the dry gas.
Then use PV = nRT to solve for the volume @ STP.

Answer 2

What do YOU think it is Dr. Bob? You obviously know it is or you wouldn't have asked that. Come onnn 🤦‍♀️

Answer 3

Thank you Ok ummm.......... Oh Hi! I needed a second reminder.
