In the laboratory, concentrated hydrogen chloric acid reacted with aluminum. Hydrogen gas was collected over water at 25 degrees Celsius and had a volume of 355 cm33 at a total pressure of 750 mm Hg. The vapor pressure of water at 25 degrees Celsius is 24 mm Hg. Find the partial pressure of hydrogen gas. ​
