Mol of HCl reacting = M(HCl)*V(HCl)
= 3.00 M * 0.168 L
= 0.504 mol
Same is the mol of NaOH reacting
So,
Q = delta H Neutralisation * number of mol
= -56.1 KJ/mol * 0.504 mol
= -28.3 KJ
Answer: -28.3 KJ

Additional Problem 6.098 Your answer is partially correct. Try again. A dilute solution of hydrochloric acid with a mass of 614.08 g and containing 0.30664 mol of HCl was exactly neutralized in a calorimeter by the sodium hydroxide in 618.91 g of a comparably dilute solution. The temperature increased from 16.663 to 19.946 °C. The specific heat of the HCl solution was 4.031 Jug-1.°C-1; that of the NaOH solution was 4.046 Jug-1.00-1. The heat capacity of the calorimeter was 77.99...
