Formula of nitric oxide (II): NO. The mass fraction is found by the formula u = A / M, where A is the relative atomic weight of the element, M is the relative molecular weight of the substance, A and M are determined according to the periodic table.
M (NO) = 14 + 16 = 30. A (O) = 16. Mass fraction of oxygen in oxide: u (O) = 16/30 = 0.53.
Answer: 0.53.
