11) What is the volume of 4.92 grams of hydrogen gas at STP? (Show the work using dimensional analysis)

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.
