Question

How many moles are there in 1.27 x 10^24 atoms of potassium

Answer 1

Step-by-step explanation:

We know that, 1 mole of any substance contain 6.022 X 10^23 atoms/molecules.

Thus, 6.022 X 10^23 atoms = 1 mole

Therefore, 1.29x10^24 =

= 2.14

Thus, 2.14 moles are present in 1.29x10^24 hydrogen atoms in HF.
