Question Completul Jualus. [CLO5] Consider again the dissolution reaction NaOH (s) + H20 (1) - Na+ (aq) + HO- (aq) in a constant-pressure calorimeter containing mw = 98 grams of water. Dissolving mNaOH=2 grams of NaOH causes a ATsol = 5 °C of the solution inside the calorimeter. Data: the molar mass of NaOH is MNaOH=40 g/mol. The specific heat capacity of liquid water at room temper- ature is cw = 4.184 J/(g°C). Hint: note that mw >> mNaOH, so...
