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.
