Answer 2

The oxidation number of Mn in $Mn_3O_4$ is 8/3.

• The oxidation number of Oxygen is -2.
• There are a total of 4 oxygen atoms that are present so the total oxidation number of oxygen is -8.
• Now the compound is neural so, the overall oxidation state is 0.
• Let the oxidation state of Mn be x.
• $3x - 8 = 0 \\ x = \frac{8}{3}$
• Thus the oxidation state of Mn is 8/3 but it exists as +3 and +2 states.
