Extracted text: 4.99 g of a solid (84.4 g mol-1) was dissolved in liquid water in a calorimeter with a calorimeter constant of 56.9J K-1. Prior to mixing everything was equilibrated to 69.6 °C. The resulting solution with a mass of 17.2 g was observed to be at a temperature of 52.0 °C and have a specific heat capacity of 4.22 J g-1 K-1. Determine g per mole for this dissolution process.
