The correct answer to this question is B, 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
