WebA "coffee cup calorimeter" containing 39.825 g of water has its initial temperature measured at 24∘C. To this calorimeter a 4.102 g sample of KNO3 is dissolved and the temperature monitored. The lowest temperature of the solution was measured at 19∘C a. WebIn a coffee-cup calorimeter, 150.0 mL of 0.50 M HCI is added to 50.0 mL of 1.00 M NaOH to make 200.0 g solution at an initial temperature of 48.2C. If the enthalpy of neutralization for the reaction between a strong acid and a strong base is 56 kJ/mol, calculate the final temperature of the calorimeter contents.
