A vessel contains 5900 oxygen molecules at 520 K having Maxwell-Boltzman distrubution function. The universal gas constant is 8.31451 J/K mol. Determine the most probable speed if the molecular mass of oxygen is 0.032 kg/ mol. Answer is m/s. Find the average speed for the molecules of the gas in m/s. Find the root-mean-square speed for the particles in the gas in m/s. I added more points since this is multiple questions. Thanks!
