SUMMARY
The reaction of 927 grams of Mg(OH)2 with phosphoric acid (H3PO4) releases 70,482 kJ of heat. This calculation is based on the stoichiometry of the reaction, where 3 moles of Mg(OH)2 yield 1427 kJ of energy. The conversion from grams to moles utilizes the molar mass of Mg(OH)2, which is 56.305 g/mol. The heat release is directly proportional to the amount of Mg(OH)2 reacted, confirming the calculations provided in the discussion.
