I think the formula of the compound is wrong. ... the correct formala is HNO3
The Oxidation number of hydrogen is +1
the Oxidation number of oxygen is -2
the sum of the Oxidation numbers of all the elements in nuetral compound is equal to zero.
H+N+3O=0
1+N+3(-2)=0
N=+5
Hence the Oxidation number of nitrogen is +5
0
