Question

The compound NH, NO, can be decomposed to form N, and H.O. This can be represented at the atomic level by a chemical equation NH NON + 2H1,0 According to the law of conservation of mass, if 28.3 grams of NH NO, decomposes and 12.4 grams of N, is formed, how many grams of H.O must simultaneously be formed? grams H2O
