Because the molecular mass of Hydrogen is 1gram/mole, there is 1 mole of hydrogen in 1 gram of hydrogen atoms.For every mole, there are 6.02*10^23 atoms so in 1 gram of hydrogen there are 6.02*10^23 hydrogen atoms (in scientific notation) this is equal to 602000000000000000000000 hydrogen atoms.

The total number of atoms in 1 gram of hydrogen is termed as a mole of hydrogen.
Detailed answer
A mole or the Avogadro number that is equivalent to 6.022 x atoms of hydrogen are present in 1 gram.
- But the atomic weight of hydrogen is 1.0079,
- The number of molecules present in 1 gram of hydrogen is 3.22Ć molecules.
- 1 u is not the exact value present in hydrogen it is almost greater than that.
- Avogadro's number is defined as the number of units that are present in one mole of a substance. They can be electrons, molecules, etc.
