  1. 6oC
  2. 5.5oC
  3. 5.50oC
  4. 5.800oC

A student mixes 50 mL of 1.0 M HCl and 50 mL of 1.0 M NaOH in a coffee-cup calorimeter and observes the change in temperature until the mixture reaches thermal equilibrium. The initial and final temperatures (oC) of the mixture are shown in the diagram to the right. Based on the results, what is the change in temperature reported with the correct number of significant figures?
