Solution: 30 mol of monoatomic hydrogen gas is contained within a 30 cm x 40 cm x 60 cm box at a pressure of 5x105 Pa.
(a) What is the rms speed of the hydrogen gas? Note that the mass of hydrogen is 1.67x10

30 mol of monoatomic hydrogen gas is contained within a 30 cm x 40 cm x 60 cm box at a pressure of 5x10^{5} Pa.

(a) What is the rms speed of the hydrogen gas? Note that the mass of hydrogen is 1.67x10 ^{-27} kg.

(b) What would the rms speed be for a 30 mol sample of O _{2} gas, considered to have a rigid inter-atomic bond, stored in the same container at the same pressure? Note that the mass of O_{2} is 5.34x10^{-26} kg.
