Question

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

Answer 1

Answer:-

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

The given number of atoms is $4.186*10^2^4$ 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:

$4.186*10^2^4 atoms(\frac{1 mole}{6.022*10^2^3 atoms})$

= 6.951 moles

Hence, 6.951 moles of Al are equivalent to $4.186*10^2^4 atoms$ .
