Question: What is the root mean square speed of gas molecules at a temperature of 300 K for a gas with a molar mass of 0.029 kg/mol?

Options:

  1. 300 m/s
  2. 400 m/s
  3. 500 m/s
  4. 600 m/s

Correct Answer: 400 m/s

Solution: 

Using the formula v_rms = sqrt(3RT/M), where R = 8.314 J/(mol·K), T = 300 K, and M = 0.029 kg/mol, we find v_rms ≈ 400 m/s.
