Question

Vapour density of gas is 11.2 volume occupied by 2.4 gms of this at STP will be-

Answer 1

Answer:

Explanation:

Heya Frnd ........ ☺

↔GIVEN THAT :-↔

VAPOUR DENSITY OF GAS = 11.2

↔TO FIND :-↔

VOLUME OCCUPIED BY 2.4 GRAMS OF THIS GAS.

↔ SOLUTION↔

We know that :-

vapour density=molar mass /2 ,

So,

Molar mass => 2 × V.D.

=> 2 × 11.2 => 22.4 g.

Now,

n (gas) = Given mass / Molar mass

=> 2.4 / 22.4

=> 0.107 moles.

Now,

n = (volume of gas at STP / 22.4)

=> 0.107 = Volume / 22.4

Therefore ,

Volume of gas is 2.4 litres,

HOPE IT HELPS YOU.
