If we place 0.00200 mol HCl (aq) and 0.00200 mol NaOH (aq) in our calorimeter with 50.0 mL (so 50 g) of water what is the final temperature of the solution? [Assume negligible mass for the HCl and the NaOH and just calculate based on the H2O. H2O has a specific heat of 4.184 J g-1 C-1. The water starts at 21.000 C]
