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!

Molecules in a sample of a gas move at a variety of speeds. Molecular speed can be described by the root-mean-square speed of the gas, which is the square root of the average of the squares of the speeds of all the gas molecules. What is the rms speed of a sample of O2 at 12.49 °C, in m/s? A typed answer is prefered. Answer should be in significant figures.
