Question 1 (1 point)
5.00 g of NaOH are dissolved in 0.100 kg of water at 20 °C. After dissolving, the final temperature was
33.2°C.
Determine the change in enthalpy (AH) in kJ/mol for NaOH.
q=m. C.AT
c=4.184 kJ/kg.
moles g + molar mass
(remember, you are calculating the AH for the water, you need to make it the opposite sign for the
crystals)
