3. Define calorimetry and describe the two commonly used calorimeters. 4. When a 1.50 g sample of solid sodium hydroxide dissolves in 60.0 g of water in a coffee-cup calorimeter, the temperature rises from 15.0°C to 32.8°C. a. Calculate the quantity of heat (in kJ) released in the reaction. b. Using your result from part (a), calculate AH (in kJ mol NaOH) for the solution process. Assume that the specific heat of the solution is the same as that of pure water (4. 184 J · g¯¹°c¯¹).
