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

unified atomic mass unit
The unified atomic mass unit, denoted u, is defined to be 1 u = 1.6605 × 10-27 kg. It can be used as an approximation for the average mass of a nucleon in a nucleus, taking the binding energy into account. How much energy, in megaelectron volts, would you obtain if you completely converted a nucleus of 15 nucleons into free energy?

Problem 4 (1 points) A proton (P) of mass 1.01 u (unified atomic mass unit) traveling a speed of 3.5x109 m/s has an elastic head on collision with a helium (He) nucleus (mwe = 4.00u) initially at rest. What are the velocities of the proton and helium nucleus after collision? Assume the collision takes place in nearly empty space. (Hint: conservation of linear momentum, elastic collision)
