Under normal atmospheric pressure, nitrogen boils (and condenses) at -196oC. When 7.5 g of nitrogen gas at -196oC was put into a dewar flask initially at -260oC, their temperatures reach -210.9oC. The specific heat capacity and heat of vaporization of nitrogen are 1.04 J/g-oC and 200 J/g.

Question
Under normal atmospheric pressure, nitrogen boils (and condenses) at -196oC. When 7.5 g of nitrogen gas at -196oC was put into a dewar flask initially at -260oC, their temperatures reach -210.9oC. The specific heat capacity and heat of vaporization of nitrogen are 1.04 J/g-oC and 200 J/g. Determine the heat capacity of the dewar flask. Input answer in two decimal places.
