Question

Convert 8.50 moles Ca to atoms

Answer 1

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

Step-by-step 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.
