Calculate the number of atoms in 4.2 moles of sulfur atoms.
Now, calculate the mass of these same 4.2 moles.
Please show work! I have no clue how to solve this.

Answer :

1 mole = 6.022*10^23 atoms
4.2 moles sulfur = 4.2* 6.022 * 10^23 sulfur atoms = 2.421*10^24 sulfur atoms

1 mole sulfur = 32.065 g sulfur
4.2 moles sulfur = 4.2 * 32.065 g sulfur = 128.901 g sulfur
