20.0 g of ammonium nitrate (NH(4)NO(3)) ...

`20.0 g` of ammonium nitrate `(NH_(4)NO_(3))` is dissolved In `125 g` of water in a coffee-cup calorimeter, the temperature falls from `296.5 K` to `286.4 K`. Find the value of `q` for the calorimeter. (Hint: heat capacity of water as the heat capacity of the calorimeter and its content)
