Hey friend,
We already know that
1 mole of any gas occupies 22.4 litres at STP.
Here,given weight of hydrogen is 20 g
Molecular weight of hydrogen is 2 g
No.of moles = given weight/molecular weight
→ = 20/2 = 10 moles
1 mole -------------22.4 litres
10 moles ------------?
→ 10 moles × 22.4 litres / 1 mole
→ 224 litres
volume of 20 g of hydrogen at STP is 224 litres
Hope it helps
