The correct answer to this question is-it has 80 mol of atoms. Mol, also known as moles or Avogardro's number, are an amount unit used in chemistry. It is the mass of a substance, which would contain the same number of units in an atom. These units could be formula units, atoms, or molecules.
The mol allows a chemist to translate atoms, ions, and molecules into grams, kilograms, and tons. It can also be used to predict how much product is needed for a specific reactant. Mol can be calculated using the following formula: 1 mole = 6.022 × 1023 particles/mol = formula weight expressed in grams
