Question

Two vessels are labeled A and B. Vessel A contains NH3 gas at 70°C, and vessel B contains Ne gas at the same temperature. If the average kinetic energy of NH3 is 7.1 10-21 J/molecule, calculate the mean-square speed of Ne atoms in m2/s2.

1/2 mass*v^2=AvgKE

meansqarespeed=2*avgKE/mass

If they are at the same temp, they have the same avgKE.
