Question

Hydrogen, oxygen and carbon dioxide are taken in containers of $2l$ volume each. Compare the ratio of the number of molecules of the three gases respectively, under same conditions of temperature and pressure.

• A. 1:8:22
• B. 1:1:1
• C. 1:16:44
• D. 1:8:44

Answer 1

Answer: (B)

1:1:1

Using ideal gas law: PV =nRT

n = $\frac{V}{RT}$

here P, R and T= Constant, V = 2l

hence number of moles also equal

the ration of moles equal to 1:1:1

answer is B
