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 -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 O2 is 5.34x10-26 kg.

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.
