18.2 g of a basic solution was mixed with 31.1 g of an acidic solution in a calorimeter with a calorimeter constant of 76.8 J K–1 with all substances initially at 27.8 °C. The resulting solution was observed to be at a temperature of 54.2 °C and have a heat capacity of 4.59 J g–1 K–1.
Determine q for the mixing process.
