Astudent uses a calorimeter to determine the enthalpy of dissolving for ammonium nitrate. the student fills a calorimeter with 475 grams of water at room temperature (24 degrees celsius). the student adds 125 grams of solid ammonium nitrate into the calorimeter and closes the lid. she allows the ammonium nitrate to completely dissolve and observes that the temperature of the water is now 7.8 degrees celsius. she knows that the specific heat of water is 4.18 j/g °c. using these data, calculate the enthalpy of dissolving (hdissolving) of the ammonium nitrate in joules per gram (j/g). work must be shown in order to earn credit..
