Open in App

Solution

The gram atomic weight of Nitrogen (N)= 14 gm
The gram atomic weight of Oxygen (O)= 16 gm
$R a t i o = \frac{G r a m a t o m i c w e i g h t o f N i t r o g e n}{G r a m a t o m i c w e i g h t o f O x y g e n}$
Substituting the values in the above formula
$R a t i o = \frac{14}{16} = \frac{7}{8}$
Therefore, the ratio of a gram atomic weight of nitrogen and oxygen is $\frac{7}{8}$ .
