(20 points) Sodium oxide reacts with water exothermically to form aqueous sodium ions and aqueous hydroxide ions. In this problem, 1.3241 grams of sodium oxide (MW=61.98g/mol) is reacted with 250grams of water initially at 75C in an adiabatic enclosure at constant pressure of 1.00atm. Specific heat of liquid water is 4.184J/g-K. What is the final temperature of the system (given that the water does not boil and assuming that enthalpy change with small change in temperature is negligible)? Below are some molar enthalpies of formation that you may find useful
