1. How many moles of potassium are present in 4.23 x 1025 potassium atoms? (show solution)
please help if u know only. ty

70.26 moles

Explanation:

1 mole of potassium will contain 6.02 x 10²³ atoms of potassium

6.02 x 10²³ atoms of potassium  = 1 mole

4.23 x 10²⁵ atoms of potassium = 4.23 x 10²⁵ / 6.02 x 10²³

= 70.26 moles .
