Suppose 160 mL of 8.0 M NaOH(aq) is added to 197 mL of 6.0 M HNO3(aq) to make a solution with a density of 1.1 g/mL and a specific heat of 4.1 J/gxK. If the initial temperature of both solutions is 295 K, what will be the final temperature (K)? Enter your answer as an integer. H+(aq) + OH-(aq) → H2O() ΔHo=-55.8 kJ/mol

Enthalpy of Neutralization Reaction: A 25.0 mL sample of 0.200 M NaOH is mixed with a 25.0 mL sample of 0.200 M HNO3 in a coffee cup calorimeter. NaOH and HNO3 will undergo Neutralization Reaction according to the following balanced equation: NaOH(aq) + HNO3(aq) --> NaCl (aq) + H2O (l) Both solutions were initially at 35.00°C and Tmax of the resulting solution was recorded as 37.00°C (from the graph). Assume 1) that no heat is lost to the calorimeter or the surroundings, and...
