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...
