A Mole of Hydrogen Gas The rule is that the mass of a particle in AMU is equal to the mass of a mole of the particles in grams. For example, the atomic mass of a hydrogen molecule (H2) is 2.016 AMU, so a mole of hydrogen gas weighs 2.016 grams. Since there are 1,000 grams in...
He established that atoms of a given element are identical in size and mass (though we now know of the existence of isotopes and varying masses). In doing so, Dalton suggested that the masses of atoms be measured relative to the lightest atom, hydrogen....
