6g of Potassium nitrate solid was added to 120cm3 of water in a plastic beaker.
The mixture was stirred gently and the following results were obtained.
Initial temperature = 21.50C
Final temperature = 17.0 0C
(a) Calculate the enthalpy change for the reaction
(Density =1g/cm3, C= 4.2jg-1K-1)
(b) Calculate the molar enthalpy change for the dissolution of potassium nitrate
(K=39, N= 14, O =16)
