9.91 g of solid NaOH is added to a calorimeter containing 250 mL of deionized water. Temperature change is recorded and the following values are determined:
Tinitial = 20.50 ºC
Tfinal = 30.72 ºC
Assume the specific heat of this solution is the same as water, 4.184 J/deg*g, and no heat was lost to the calorimeter.
Molar mass of NaOH = 39.997 g/mol
Refer to the information in the course materials for determining the heat of solution of a salt, and determine the molar enthalpy of solution for NaOH.
