2. When 4.21 grams of potassium hydroxide are added to 250. mL of water in a coffee cup calorimeter, the temperature rises by 4.14 °C. Assume that the density and specific heat of the dilute aqueous solution are the same as those of H2O and calculate the molar heat of solution of potassium hydroxide in kJ/mol. C = 4.184 J/g K
