## Homework Statement

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.

## Homework Equations

PV=nRT

PV/NT=PV/NT

standard pressure=760 mm Hg or 1 atm

standard temperature= 273 Kelvin

## 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?
