Question

A 100.0mL solution of 1.05 H₂SO₄ at 23.2degrees Celcius is mixed with 100.0mL of 2.0 M NaOH, also at 23.2degrees Celcius, in a coffee-cup calorimeter. After the reactionoccurs, the temperature of the resulting mixture is 35.7 degreesCelcius. The density of the final solution is 1.06g/mL. Calculatethe molar heat of neutralization. Assume the specific heat of thesolution is 4.184 J/g*C. The heat capacity of the calorimeter is32.5 J/C.

(1/2)H₂SO₄ (aq) + NaOH(aq) =>(1/2)Na₂SO₄ (aq) + H₂O(l)

a. 41.7 kJ/mol

b. 57.5 kJ/mol

c. 45.9 kJ/mol

d. 13.0 kJ/mol

e. 33.9 kJ/mol
