A sample of NaOH (MM = 40.00 g/mol) with a mass of 1.811 g was added to a solution of HNO3 in a coffee cup calorimeter for a final volume of 100.0 mL. If both solutions were initially at 24.5 °C and the temperature of the resulting solution was recorded as 27.0 °C, determine the AH°rxn (in units of kJ/mol NaOH) for the neutralization reaction between aqueous NaOH. Assume that the density and the heat capacity of the resulting solution are the same as water, 1.00 g/mL and 4.184 J/(g x °C) respectively.

Transcribed Image Text:A sample of NaOH (MM = 40.00 g/mol) with a mass of 1.811 g was added to a
solution of HNO3 in a coffee cup calorimeter for a final volume of 100.0 mL. If both
solutions were initially at 24.5 °C and the temperature of the resulting solution was
recorded as 27.0 °C, determine the AH°rxn (in units of kJ/mol NaOH) for the
neutralization reaction between aqueous NaOH. Assume that the density and the
heat capacity of the resulting solution are the same as water, 1.00 g/mL and 4.184
J/(g x °C) respectively.
