Suppose that helium atoms in a seal container start with the same speed: 2.74 x 104 cm/s. The atoms are then allowed to collide with one another until the Maxwell distribution is established. What is the temperature of the gas at equilibrium? Assume that there is no heat exchange between the gas and its surroundings.
So the equation used to solve for this is T = mv2/3KB but I'm confused about why the mass is converted from amu to kg with 1.661 x 10-27 kg/amu. Why would we not use the molar mass in this case?
