Question

How many atoms would be in 5.00 moles of potassium

Answer 1

2.1077×10^25 atoms

Step-by-step explanation:

Since one molecule of K2SO4 contains 7 atoms {Two Potassium(K), One Sulphur (S) and Four Oxygen (O)}.

Thus in 5 moles there will be,

6.022 × 10²³ × 7 × 5 =

210.77 × 10²³ or 2.1077 × 10²⁵ or 21077 × 10²¹ atoms.

Here, 6.022 × 10²³ is the Avogadro number.
