The units for c, the specific heat of the water in the calorimeter, are J/(g K) The units for AT can be "C. Explain why the difference in units is permissible.
- A student using a calibrated solution calorimeter measured a temperature decrease of 1.10 K when 1.00 g of KNO3 was added to 74.40 g of deionized water in the calorimeter. The specific heat capacity of the solution calorimeter was found to be 4.15 J/g K. Calculate the experimental value of the molar heat of solution of KNO3, AHsoln (kJ/mol). Was the dissolution of this salt exothermic or endothermic?
