A 100.0 mL sаmple оf 0.300 M NаOH is mixed with а 100.0 mL sample оf 0.300 M HNO3 in a cоffee 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 (1.00 g/mL) and the heat capacity (4.18 J/g°C) of the resulting solution are the same as water.
