The definition of Avogadro's number of 6.022 × 1023/mole is the number of atoms or molecules per one gram atomic weight. For one gram atomic weight of hydrogen with an atomic weight of one gram, one mole of hydrogen contains 6.022 × 1023 hydrogen atoms. 1.45⋅6.02⋅1023≈8.73⋅1023 hydrogen atoms.
1 mole:
The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).
in an H:
H: 2×2×4=16 atoms of hydrogen. C: It only appears once and without a subscript, so 1×4=4 . O : Like carbon, it's 1×4=4 .
1.00 mole:
One mole is equal to 6.02214179×1023 atoms, or other elementary units such as molecules.
Hi there, so I believe your answer is 6.02⋅1023 hydrogen atoms
