Calculate q

A cylinder contains 250 g of Helium at 200 K. The external pressure is constant at 1 atm. The temperature of the gas inside the cylinder is then lowered by 97 K.

Calculate q for this system in response to the change made.

Include units of J when entering your answer.

Heat capacity for Helium = 20.8 J/(mol K)

Molecular weight for Helium = 4 g/mol

Same process as for the other question like this, just different value.
