As we learnt ,

 

Gay Lussac's law of Gaseous Volumes -

When gases combine or are poduced in a chemical reaction, they do so in a simple ratio by volume provided all gases are at the same temperature and pressure.

- wherein

H_{2}}_{(g)} + {O_{2}}_{(g)} \rightarrow {H_{2}O}_{(g)}

100 ml        50ml            100ml

 

 \frac{N_{N_{2}}}{N_{O_{2}}} = \frac{\frac{1}{32}}{\frac{4}{28}} = \frac{7}{32}

 


Option 1)

1 : 4
 

Option 2)

7 : 32

Option 3)

1 : 8

 

Option 4)

3 : 16
