Two tanks of gas, one of hydrogen, H2, and one of helium, He, contain equal masses of gas. The gram-molecular mass of He is twice that of H2 . Both tanks of gas are at the same temperature, 293 K. Which statement(s) below is(are) correct when we ignore vibrational motion?
 a. The total internal energy of the hydrogen is the same as that of the helium.
  b. The total internal energy of the hydrogen is 167 times that of the helium.
  c. The total internal energy of the helium is 1.67 times that of the hydrogen.
  d. The total internal energy of the hydrogen is 3.33 times that of the helium.
  e. The total internal energy of the helium is 3.33 times that of the hydrogen.
