Helium atoms have a mass of 4u and oxygen molecules have a mass of 32u, where u is defined as an atomic mass unit (u=1.660540×10?27kg). Compare a gas of helium atoms to a gas of oxygen molecules. At what gas temperature Trms would the root-mean-square (rms) speed of a helium atom be equal to that of an oxygen molecule in a gas at 300 K? The answer is not 300 or 37.5
