A 1000 ML Sample of 0

A 100.0 mL sample of 0.300 M NaOH is mixed with a 100.0 mL sample of 0.300 M HNO₃ in a coffee cup calorimeter.If both solutions were initially at 35.00°C and the temperature of the resulting solution was recorded as 37.00°C,determine the ΔH°_rxn (in units of kJ/mol NaOH) for the neutralization reaction between aqueous NaOH and HCl.Assume 1) that no heat is lost to the calorimeter or the surroundings,and 2) that the density and the heat capacity of the resulting solution are the same as water.

A) -55.7 kJ/mol NaOH
B) -169 kJ/mol NaOH
C) -16.7 kJ/mol NaOH
D) -27.9 kJ/mol NaOH
E) - 34.4 kJ/mol NaOH
