Question

A 100.0 mL room temperature sample of 0.500 M NaOH is mixed with a room temperature 100.0 mL sample of 0.500 M HNO3 in a "coffee cup" calorimeter. The initial temperature was 21.7 °C and the final temperature after the reaction completed was measured to be 25.1 °C. The chemical reaction is given below: 
HNO3(aq) + NaOH(aq) ➜ NaNO3(aq) + H2O (l) 
Assume that the density of all the solutions is 1.000 g/mL and that the specific heat of all the solutions is 4.184 J/g°C. 
What is the amount of heat gained by the solution? 
Round answer to 4 significant figures.
