4 100% 5g of ammonium nitrate was dissolved in 60g of water in an insulated container. The temperature at the start of the reaction was 23.0°C and at the end it was 19.0°C. Use the equation below to calculate the energy absorbed by the reaction. (Hint: the mass of the solution changes when ammonium nitrate is added.)
