How many moles of aluminum are equivalent to 4.816 × 10^24 atoms?

-

Solution:- To convert atoms to moles we divide the number of atoms by Avogadro number.

The given number of atoms is and we are asked to calculate the number of moles of Al that are equivalent to these number of atoms. Let's divide the atoms by Avogadro number:

= 6.951 moles

Hence, 6.951 moles of Al are equivalent to .
