A mixture of 2.0 mol of H2(g) and 1.0 mol of O2(g) is placed in a sealed evacuated container made of a perfect insulating material at 24 ∘C. The mixture is ignited with a spark and it reacts to form liquid water. (The specific heat for water vapor is 2.04 J/g⋅oC, and ∆Hvap = 44.0 kJ/mol)

The heat generates in the exothermic reaction will heat the liquid water to boiling, vaporize it, and heat the vapor to its final temperature. Calculate the final temperature of the water vapor.

Tf = ___ oC
