Question- A sample of hydrogen gas is mixed with water vapor. The mixture has a total pressure of 755 Torr and the water vapor has a partial pressure of 24 Torr. What amount of hydrogen gas (in grams) is contained in 1.55 L of this mixture at 298 K?
Please illustrate work as well as walk me during the problem so that I can follow and understand it.
