1. The problem statement, all variables and given/known data Hydrogen gas is collected over water at 25°C. The atmospheric pressure in the room is 745 mm Hg and the volume of gas in the container is 43.5mL. The vapor pressure of water at 25°C is 23.8 mm Hg. Determine the volume the gas would occupy at STP. 2. Relevant equations PV=nRT PV/NT=PV/NT standard pressure=760 mm Hg or 1 atm standard temperature= 273 Kelvin 3. The attempt at a solution Well for this one I wasn't really sure if they just gave me excess information to throw me off. My first response was to say that the volume would just be 43.5mL. None of the equations provided above worked with just the information given. Is this really as easy at it seems?
