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 [tex](H_{2} )[/tex] = [tex]1\times 2 = 2[/tex].
Moles of hydrogen gas = [tex]\frac{weight}{molecular weight} = \frac{4.92}{2} = 2.46[/tex] moles.
At STP, 1 mole of hydrogen gas = occupies 22.4 litter
So, 2.46 mole of hydrogen gas = occupies [tex]\frac{22.4}{2.46} = 9.105[/tex] litter.
Hence, the volume of 2.46 grams of hydrogen gas at STP is 9.105 litter.
