Molar mass of Hydrogen molecule (H₂) = 2 g
No : of moles = 0.5 moles
No : of moles = given mass / molar mass
mass = molar mass × no: of moles
= 2 × 0.5
mass = 1 g

Answer:
Molar Mass of Hydrogen gas (H2) = 2
No. of Moles= 0.5
No. of Moles = Given Mass / Molar Mass
0.5 = Given Mass /2
0.5 X 2 = Given Mass
Given Mass = 1 g
Hence, Mass of 0.5 mole of H2 gas is 1g.
