Ammonium nitrate decomposes to give dinitrogen monoxide and water as shown in the following reaction: NH₄NO₃ $\rarr$ N₂O + 2H₂O
If a 108 g sample of NH₄NO₃ decomposes to give 23 g of N₂O(g) , what percent of the original sample remains

Question

Ammonium nitrate decomposes to give dinitrogen monoxide and water as shown in the following reaction: NH₄NO₃

\rarr

N₂O + 2H₂O
If a 108 g sample of NH₄NO₃ decomposes to give 23 g of N₂O(g) , what percent of the original sample remains

Quizplus · Accepted Answer

The mass of NH₄NO₃ that decomposes is 108 g - 23 g = 85 g. The percentage of the original sample that remains is (85 g / 108 g) * 100% = 78.7%. Therefore, 100% - 78.7% = 21.3% decomposed, so 61% remains.
