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-1°C-1, calculate ΔH for the reaction, as written.

2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)
