molar mass of Hydrogen gas = 2g
mass of 0.5 moles of H2 gas = 2 * 0.5 = 1g
mass of 0.5 moles of H2 gas = 2 * 0.5 = 1g

No : of moles = 0.5
Molar mass of H₂ = 2 g
No : of moles = Given mass / Molar mass
∴ Mass = No : of moles × Molar mass
= 0.5 ×2
= 1 gram
Molar mass of H₂ = 2 g
No : of moles = Given mass / Molar mass
∴ Mass = No : of moles × Molar mass
= 0.5 ×2
= 1 gram
