What is the oxidation number of metal in pyrolusite ore?

Answer:

4.00

Solution:

Pyrolusite is primarily manganese dioxide (MnO₂). Oxygen typically has an oxidation number of -2. Since there are two oxygen atoms, their total contribution is $2 \times (- 2) = - 4$ . For the compound to be neutral, the oxidation number of manganese (Mn) must be +4.
