A chemist conducts an experiment in which 2.00 L of hydrogen gas is collected over water at 1.00 atm and 298.15 K.
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 298.15 Kis 0.0300 atm.
Using Dalton's Law, calculate the pressure of the hydrogen gas in
atm.
