Question

Four identical containers are filled with N2, Ne, CO2 and NH3 at same
temperature and pressure respectively Ratio of number of atoms in the containers
will be in the order of
(A)1:1:1:1
(B) 2:1:4:3
(C)2:1:3:4
(D) 1:1:2:2​

Answer 1

Answer:

The ratio of number of atoms of all the gases filled in different containers is =      

(A) 1:1:1:1

Reason - molecules have the same number of atoms

Answer 2

Answer:

The ratio of the number of atoms in the containers will be 2: 1 : 3: 4.

So the correct option will be (C)

Explanation:

According to Avogadro's law, all the gase having the same volume at constant temperature and pressure will have the same number of moles.

Therefore, $N_{2}$, $CO_{2}$, $Ne$, and $NH_{3}$ will have the same number of moles.

But,

The number of atoms in  $N_{2}$ is 2.

The number of atoms in Ne is 1.

The number of atoms in $CO_{2}$ is 3.

The number of an atom in $NH_{3}$  is 4.

Therefore, the ratio of the number of atoms in containers will be 2: 1 : 3: 4
