Avogadro's Number: The number 6.022 x 1023 is the value of the Avogadro's number. It is the number of particles or substance in one mole. For example, there are 6.022 x 1023 atoms in one mole of hydrogen.

one gram of hydrogen contains one mole of hydrogen as its atomic weight is 1. One mole is 6.02x10^23 atoms. But, hydrogen is diatomic, meaning its atoms are found in pairs so, the amount of molecules would be 3.01x10^23.

Answer. Answer: One mole of any substance contains Avogadro's number of atoms = 6.022 x 10^23 atoms. So multiply number of moles x number of atoms/mole = 1.8066 x 10^24 atoms of H2.

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.
