B) are compressible.
Explanation:
The three members of the noble gas family are all compressible in nature and they are monoatomic gaseous molecules.
There are three states of matter which are:
Solid
liquid
Gases
Gases are random matter that have not fixed shape and volume. This implies that they can easily fit into any container they are placed into. Their state of motion is randomized and they are free to move in all directions colliding with one another and the walls of their container.
When pressure is applied to them, they get compressed and takes up the shape of any vessel they are in.
Gases are the only compressible state of matter.

Answer:
The volume of 4.92 grams of hydrogen gas at STP is 9.105 litter.
Explanation:
We know that, the molecular weight of hydrogen gas 
= 
.
Moles of hydrogen gas = 
moles.
At STP, 1 mole of hydrogen gas = occupies 22.4 litter
So, 2.46 mole of hydrogen gas = occupies 
litter.
Hence, the volume of 2.46 grams of hydrogen gas at STP is 9.105 litter.
