Given the thermochemical equation below, calculate the amount of energy released when 250. g of NaOH (molar mass = 40.0 g/mol) reacts with an excess of HCl. Report answer to the correct number of significant figures in units of kilojoules, kJ.
NaOH + HCl --> NaCl + H2O deltaH = -56.2 kJ/mol
NaOH + HCl --> NaCl + H2O deltaH = -56.2 kJ/mol
