Final temperature of the gas mixture,neglecting heat losses

  1. Oct 13, 2014 #1
    A box containing 2 moles of rigid diatomic gas molecules at temperature T connected to another box containing 2 moles of ideal monoatomic gas at temperature 5T. What is the final temperature of the gas mixture,neglecting heat losses?



    2. The attempt at a solution:
    Q(initial)=Q(final)
    m1C(v1)T(1)+m2C(v2)T(2)=(m1+m2)C(v)T(final)
    but i dont know m1 & m2.
