Question

Given the reaction:

HCl + NaOH -> H2O + NaCl

Mass of 2.0 M HCl = 50.0 g

Mass of 2.0 M NaOH = 50.0g

Temperature of HCl before mixing = 24 celsius

Temperature of NaOH before mixing = 24 celsius

Temperature after mixing both = 37 celsius

Q solution = 2719.6 J

Q calorimeter = 679.9 J

Total heat of neutralization = -3399.5 J

Moles of acid reacted = 0.1 mole

Moles of water produced = 0.1 mole

Calculate the heat of neutralization per one mole of water formed = ____________ kJ/mole
