Molar Mass of the NO = 14 g/mol + 16 g/mol = 30 g/mol
Number of mols is 2.79 g = 2.79mol/30g/mol = 0.093 mol
Heat released by the decomposition of 0.093 mol = 92.29kj/mol * 0.093 mol = 8.58 kj (you might include a negative sign to indicate tha the heat is released)

Explanation:
Hello,
In this case, for the described chemical reaction:
2 HCl(aq) + Mg(OH)2(aq) → MgCl2(aq) + 2 H2O(l)
We can notice there is a 2:1 molar ratio between the moles of hydrochloric acid and magnesium hydroxide, therefore, at the equivalence point:
And in terms of volumes and concentrations we verify:
So we use the given data to proof it:
Therefore, we can conclude the data is wrong by means of the 2:1 mole ratio that for sure was not taken into account. This is also supported by the fact that normalities are actually the same, but the nomality of magnesium hydroxide is the half of the hydrochloric acid normality since the acid is monoprotic and the base has two hydroxyl ions.
Best regards.
