Is this molecules of hydrogen gas (H2) or just hydrogen atoms (H). If it's molecules it will be 1/2 of avogadro's number.
3.01x10^23
Hydrogen is diatomic

Since a mole of hydrogen contains about 6 X 10^23 atoms and a mole of hydrogen weighs about 2 grams ( H2). You can now do the rest and figure out how much a gram weighs

Look up Avagodro' hypothesis. 6.06x10to23 per molecular weight
