Calculate the mass fraction of elements in the substance HNO2. The elemental composition of the substance is as follows: mass fraction of the element iron 72.41%, oxygen 27.59% Derive the chemical formula
1) Mass fraction of elements in HNO2:
W (H) = 1/47 = 0.021 = 2.1%
W (N) = 14/47 = 0.298 = 29.8%
W (O) = 32/47 = 0.681 = 68.1%
2) Formula: Fe3O4 (Iron Scale)
