The rms speed of the molecules of a gas at 137°C is 183 m/s. Calculate the mass of a single molecule in the gas.
Answer in kg.
If He gas has an average kinetic energy of 7690 J/mol under certain conditions, what is the root mean square speed of Cl2 gas molecules under the same conditions? Answer in m/s -What would the pressure, P, of a gas be if the mean free path was 133 cm? Assume the gas is at room temperature, T = 22.6°C, and the diameter of the molecule is d = 1.50 × 10-10 m.
Answer in Pa
