Question

Four 1-1 litre flasks are separately filled with the gases $H_2,He,O_2$ and ozone. The ratio of total number of atoms of these gases present in different flask would be :

• A. 1 : 1 : 1 : 1
• B. 1 : 2 : 2 : 3
• C. 2 : 1 : 2 : 3
• D. 3 : 2 : 2 : 1

Answer 1

The correct option is C 2 : 1 : 2 : 3

According to Avogadro's law, all gases at same temperature and pressure will contain same number of molecules. Hence, number of molecules of all gases will be same bt ration of atoms of each gases will $2:1:2:3$.
