Answer:

The volume of 4.92 grams of hydrogen gas at STP is 9.105 litter.

Step-by-step explanation:

We know that, the molecular weight of hydrogen gas
(H_(2) ) =
1* 2 = 2.

Moles of hydrogen gas =
(weight)/(molecular weight) = (4.92)/(2) = 2.46 moles.

At STP, 1 mole of hydrogen gas = occupies 22.4 litter

So, 2.46 mole of hydrogen gas = occupies
(22.4)/(2.46) = 9.105 litter.

Hence, the volume of 2.46 grams of hydrogen gas at STP is 9.105 litter.
