At sea level, the atmospheric pressure is approximately 1 atm. What is the partial pressure of oxygen (O_2) in dry air at sea level?

Which law relates the partial pressure of a gas to the total pressure of a gas mixture?

A gas moves from an area of ________ partial pressure to an area of ________ partial pressure.

A container holds a mixture of helium (He) and neon (Ne) gases at a total pressure of 2.0 atm. If the mole fraction of He is 0.25 and the mole fraction of Ne is 0.75, what are the partial pressures of He and Ne, respectively?
