Final answer:
There are 79.7 moles of tungsten atoms in 4.8 x 10^25 tungsten atoms, calculated by dividing the total number of atoms by Avogadro's number (6.022 x 10^23 atoms/mol).
Step-by-step explanation:
To determine how many moles of tungsten atoms are in 4.8 x 10^25 atoms, we utilize Avogadro's number, which states that one mole of any substance contains 6.022 x 10^23 representative particles (atoms, molecules, etc.). To perform the conversion, we divide the total number of tungsten atoms by Avogadro's number.
The calculation would be:
(4.8 x 10^25 atoms of W) / (6.022 x 10^23 atoms/mol) = 7.97 x 10^1 mol of W
Therefore, there are 79.7 moles of tungsten atoms in 4.8 x 10^25 atoms.
