A chemist conducts an experiment in which 2.0 L of hydrogen gas is collected over water at 1 atm and 298 K. a) The phrase 'over water" means that the gas was collected by bubbling it into an inverted bottle filled with water, which is sitting in a water bath. The gas is trapped in the bottle, displacing the water into the water bath. However, the gas collected is now saturated with water vapor. The partial pressure of water vapor at 298 K is 0.03 atm. Using Dalton's Law, calculate the pressure of the hydrogen gas in atm. b) Using the combined gas law, calculate the volume in L of the dry hydrogen gas at 273 K and a pressure of 1 atm.
