A gas has a vapour density 11.2. The volume occupied by gram of the gas at STP will be:

A

11.2 L

B

22.4 L

C

1 L

D

10 L

Text Solution

Verified by Experts

The correct Answer is:
C
Number of moles `= ("Mass")/("Molar mass")`
`= ("Mass")/(2 xx " Vapour density")`
`= (1)/(2 xx 11.2) = (1)/(22.4)`
Volume of gas `= n xx 22.4 L`
`= (1)/(22.4) xx 22.4 L = 1L`

Atoms and molecules are so small in size that it is neither possible to count them individually nor possible to determine their mass. These are counted collectively in terms of Avogadro's number. The mass of Avogadro's number of atoms and molecules is known as gram atomic mass and gram molecular mass respectively. The volume occupied by Avogadro's number of molecules of a gas or vapours is known as molar volume. The vapour density of a gas is 11.2. The volume occupied by 11.2 g of gas at NTP will be
