Mass of one atom of helium

WebDETAILS… The mass of one Avogadro number of helium atoms is 4 grams. One Avogadro number is equivalent to one mole of a substance; therefore, this question is actually asking for the mass of one mole of the helium atom. 1 Avogadro number = 6.02 × 10²³particles/mol. Mass of 6.02 × 10²³particles of helium = mass of 1 mole of He = 4grams WebA property closely related to an atom’s mass number is its atomic mass. The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu. By definition, an atom of …
