Pierce Durham · Answer 1

8.50 moles is equal to 5.1187*10²⁴ atoms of Ca.

Explanation:

We have to multiply the moles of Ca by the Avogadro's number:

= 6.022*10²³

So the number of atoms:

= 8.5 moles * 6.022*10²³atoms / mol

= 5.1187*10²⁴ atoms

Hence the 8.50 moles is equal to 5.1187*10²⁴ atoms of Ca.
