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

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.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
