Understanding the Relationship

* Avogadro's Number: One mole of any substance contains 6.022 x 10^23 particles (atoms, molecules, etc.). This is known as Avogadro's number.

Calculation

1. Set up a conversion factor:

(1 mole Zn / 6.022 x 10^23 atoms Zn)

2. Multiply the given number of atoms by the conversion factor:

1.6310 x 10^24 atoms Zn * (1 mole Zn / 6.022 x 10^23 atoms Zn)

3. Cancel out the units of "atoms Zn" and perform the calculation:

(1.6310 x 10^24 / 6.022 x 10^23) moles Zn ≈ 2.71 moles Zn

Answer: There are approximately 2.71 moles of zinc in 1.6310 x 10^24 atoms.
