Q. A tank used for filling helium balloons has a volume of 0.6  m 3  and contains 2.0 mol of helium gas at 20.0 ° C . Assuming that the helium behaves like an ideal gas
(i) What is the total translational kinetic energy of the molecules of the gas?
(ii) What is the average kinetic energy per molecule?

Dear Student


K.E. =32kBTWhere kB is called Boltzmann's constant and is equal to ratio of the gas constat R andAvogadro constant NAkB=RNAAlso, NA=Mm=Molecular weight of gasMolecule weightSubstituting valueskB=mRMK.E. =32mRMT=32nRT
