Question

100 ml O₂ and H₂ kept at same temperature and pressure.
What is true about their number of molecules
(a) NO₂ > NH₂
(b) NO₂ < NH₂ (c) NO₂ = NH₂
(d) NO₂ + NH₂ = 1 mole

Answer 1

NO₂ = NH₂

Explanation:

Gas laws explains about the all conditions of pressure, temperature and composition of gases

From the given data it is observed that, 100 ml O₂ and H₂ kept at same temperature and pressure.

In gas laws,

Avogadro's law states that "At the same temperature and pressure equal volumes of gases contain equal number of moles.

The volume of both the gases is same at the same temperature and pressure.

Hence the two gases contain equal number of molecules.

That is $NO_2=NH_2$

Hence, the correct answer is option (c)
