wrong answer would be reported​

Answer 1

Answer:

question is incorrect

Explanation:

vp is given 8 ans 1.26

Answer 2

The volume occupied by the gas is $33.6 litre$ at STP

Explanation:

Given -

• The vapour density of a gas is 8
• Number of molecules in 6.72 g of the gas

The Molecular mass of the gas is = $2$× Vapour density

• Gram molecular mass of the gas is =16gm
• 16 gm of gas at STP will occupy 22.4 litre at STP
• Thus 24 gm of gas at STP will occupy $=\frac{24}{16}$×$22.4$
• It will occupy $33.6 litre$ of gas

Thus the volume occupied by the gas is $33.6 litre$at STP
