A container of volume 0.39 m3 contains 8.7 mol of argon gas at 32◦C. Assuming argon behaves as an ideal gas, find the total internal energy of this gas. Answer in units of J.Given: R = 8.31451 J/mol • K.

  • physics -

    Internal energy per mole = Cv*T (for ideal gases), and
    = (3/2) R T for monatomic gases (like argon)

    Since you know the number of moles, you don't need to know the volume.
