Calculate the mass fraction of nitrogen in the substance NH3 (or maybe the mass fraction of the yield of the substance?)
| November 28, 2020 | education
1.Find the molar mass of NH3
M (NH3) = 14 + 1 * 3 = 17 g / mol
2. Find the mass fraction of nitrogen by the formula
ω (substances) = Ar (substances) / M (compounds)
ω (N) = 14/17 = 85.353%
Answer: the mass fraction of nitrogen in ammonia is 85.353%
