### 6th edition 8.31

8.31 Calculate the heat released by 5.025 g of Kr(g) at
0.400 atm as it cools from 97.6 oC to 25.0 oC at (a) constant pressure and (b) constant volume. Assume that krypton behaves as an ideal gas.

I don't really know where to start with this problem or what equations to even use.

Treat this problem as you would any heat capacity problem. You should be using the relations and just as you would use the equation for ordinary heat capacity problems. You can find the equations for Cp and Cv on the equation sheet.

I was stuck on the same question. So we have to convert the given mass of the krypton gas into moles and work from there?
