A flask contains 1.00 mole of oxygen gas,O₂,at 0.00 °C and 1.013 × 10⁵ Pa.What is the rms speed of the molecules? Note: the atomic mass of O is 16 u.

Question

Quizplus · Accepted Answer

The rms speed (v_rms) is calculated using the formula v_rms = sqrt(3kT/m), where k is the Boltzmann constant, T is the temperature in Kelvin, and m is the mass of a molecule. For O₂, m = 32 u = 32 x 1.66 x 10^-27 kg. At 0°C (273 K), v_rms ≈ 460 m/s.
