1. Avogadro's Number
* Avogadro's number tells us the number of particles (atoms, molecules, etc.) in one mole of a substance. It's approximately 6.022 x 10^23 particles/mol.
2. Calculation
* To find the number of atoms in 80.0 mol of zirconium, multiply the number of moles by Avogadro's number:
Number of atoms = (80.0 mol) * (6.022 x 10^23 atoms/mol)
= 4.82 x 10^25 atoms
Therefore, there are approximately 4.82 x 10^25 atoms in 80.0 mol of zirconium.
