Question

How many atoms are present in 2 litre H2 gas?

Answer 1

Answer:

1 mole of H2 molecules = 6.023 X 10 ^23 (H2 molecule)= 22.4 liters of volume of H2 gas

1 mole of H2 molecules = 1 mole of H atom +1 mole of H atom (because there are two atoms of hydrogen in hydrogen gas)

1 mole of H2 molecules = 1 mole of H atom +1 mole of H atom

1 mole of H2 molecules = 1g + 1g = 2g

22.4 liters of H2 gas = 2g

1 liter of H2 gas = 2/22.4 g

1 liter of H2 gas = 0.0893 g

1 liter volume of H2 gas contains 0.0893 g of H2 gas (in terms of mass)
