Determine the mass fraction of nitrogen in nitric oxide (IV)
| November 29, 2020 | education
formula of nitric oxide – NO2
the mass of nitrogen (N) in the compound is 14, the mass of oxygen (O) is 16 × 2 = 32
the “final mass” of nitric oxide was 14 + 32 = 46
find the mass fraction of nitrogen:
w (N) = 14: 46 = 0.30
in percentage this is 0.30 × 100 = 30%
answer: w (N) = 30%
