10.0 grams of solid sodium hydroxide (NaOH) was dissolved in 50.0 mL of water. The solution was stirred and the temperature difference was measured after 1 minute. This was filmed using an IR thermal imaging camera.
Initial temperature: 18.5C
Final temperature: 50.0C
Calculate the experimental molar enthalpy pf solution in kJ/mol. (Assume the specific heat of the solution is 4.184 J/gC)
Hint: Use the total solution mass when calculating Q
