Question - The deltaH for the dissolution of solid sodium hydroxide in water is -44.4 kJ/mol. What is the final temperature of a solution when 13.9 g of NaOH dissolves in 250.0 g of water in a coffee-cup calorimeter. The initial temperature is 23.0 °C. Assume that the mass of the solution is the sum of the masses of the solute and solvent. The specific heat of the solution is 4.184 J/g-°C.
