Sodium metal reacts with water to produce hydrogen gas and sodium hydroxide according to the chemical equation shown below. When 0.015 mol of Na is added to 100.00 g of water, the temperature of the resulting solution rises from 25.00°C to 31.45°C. If the specific heat of the solution is 4.18 J/(g ∙ °C), calculate ΔH for the reaction, as written.

   2 Na(s) + 2 H2O(l) → 2 NaOH(aq) + H2(g)   ΔH = ?     

A) -5.41 kJ
B) -90.0 kJ
C) -180 kJ
D) -360 kJ
