923.85 grams of gaseous ammonia condenses into liquid.How much energy was released?

answer: 1268.28852 = 1268 kj

    When you post a problem like this you should tell us what you used for the heat vaporization. Not all sources give the same number. Using 23.25 kJ/mol I obtained 1263.5 kJ which I would round to 1264 kJ.
