Hydrogen gas generated in laboratory experiments is usually collected over water. It is called a “wet gas” when collected in this manner because it contains water vapor. A sample of “wet” hydrogen at 25°C fills a 125-mL flask at a pressure of 769 mm Hg. If all the water is removed by heating, what volume will the dry hydrogen occupy at a pressure of 722 mm Hg and a temperature of 37°C? (The vapor pressure of water at 258C is 23.8 mm Hg.)
