Question

10 grams of each O2
, N2
and Cl2
are kept in three bottles. The correct order of arrangment of bottles containing

decreasing number of Molecules.

1) O2
, N2
, Cl2

2) Cl2
, N2
, O2

3) Cl2
, O2
, N2

4) N2
, O2
, Cl2​

Answer 1

Answer:

Option (4)

Explanation:

HERE IF WE CONVERT All iNTO MOLE AND THEN BY MULTIPLYING IT BY AVAGADRO NUMBER WE CAN FIND OUT WHICH ONE HAS MORE MOLECULES

1 ) 10 gm O2 → 10/32 mole = ( 10 × nA )/32 molecules

2 ) 10 of N2 → 10/28 mole = (10×nA ) /28 molecules

3 ) 10gm of Cl2 → 10/71.5 = (10×nA)71.5

Thus , On comparing N2> O2>Cl2
