¿A cuantos gramos equivalen 160 litros de H2 en CNPT? Urgente por favor, gracias

Can you me with this i really appreciate it

The bond energy for the van der waals bond between two helium atoms is 7.9×10−4ev. assuming that the average kinetic energy of a helium atom is (3/2)kbt, at what temperature is the average kinetic energy equal to the bond energy between two helium atoms
