5cm^3 of 0.10monl/dm^3 of potassium manganate (VII) reacts with 12.0cm^3 of nitrogen monoxide at rtp. A colourless solution containing a brown precipitate of manganese (IV) oxide, MnO2 was produced. Determine the final oxidation number of nitrogen in the compound and hence suggest a possible formula of the nitrogen-containing product of the reaction.

Tips :
1. Work out the moles of electrons transferred, based on the moles of oxidizing agent used.
2. Work out the moles of electrons transferred per mole of NO.
3. Based on initial OS of N in NO, and the moles of electrons transferred per mol of NO, work out the final OS of N in the product.
4. Based on the final OS of N, list out all possible N containing species with this OS.
