How many moles are there in 4.3X 10^24 atoms of He

Hey there!

There are 6.022 x 10²³ atoms in one mole.

We have 4.3 x 10²⁴ atoms of Helium. 

To find the amount of moles, we divide the number of atoms by the number of atoms in each mole.

(4.3 x 10²⁴) ÷ (6.022 x 10²³)  

We get 7.1.

This means there are 7.1 moles in 4.3 x 10²⁴ atoms of He.

Hope this helps!
