Web5.9749 x 10 23 atoms H / 1.0000 g H. Answer 2: Because the molecular mass of Hydrogen is 1 gram/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.
