Question 10

In an experiment, it was found that 0.56 g of nitrogen reacted completely with 1.28 g of oxygen to form a nitrogen oxide.

The relative formula mass ( $M_r$ ) of this nitrogen oxide is 92.

Deduce the molecular formula of this nitrogen oxide.

You must show your working. (relative atomic masses: $N=14\text{N} = 14$ , $O=16\text{O} = 16$ )
