Answer

B

Explanation

This problem requires knowledge of the concept of a mole, which is a unit of measure in chemistry. The question wants to convert atoms of tungsten into moles of tungsten. Remember Avogadro's number, 6.02214076 × 10²³, is the number of entities (e.g., atoms, ions, molecules) in a mole of a substance. Dividing the given number of atoms (4.8E25) by Avogadro's number will yield the number of moles. Among all the choices, option B gives the approximate value close to this result.
