Question

Four 1-1 litre flasks are separately filled with the gases H2, He, O2 and O3 at the same temperature and pressure. 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

Answer: (C)

2 : 1 : 2 : 3

Answer 2

(3)

H2 : He : O2 : O3

Ratio of total no. of molecules

= 1 : 1 : 1 : 1

So ratio of total no. of atoms

= 2 : 1 : 2 : 3
