How many moles of helium are 8.84×1024 atoms of he?

14.68 moles of He

Explanation:

To do this, just remember Avogadro's Constant or Avogadro's number. This constant tells us how many units ( in this case atoms) there are in a mole of ANY type of substance.

Avogadro's constant is 6.022140857 × 10²³ units per mole.

Now that we know how many atoms there are in 1 mole, we can use this as our conversion factor.

8.84 x 10²⁴ atoms of He →  moles of He

So the answer would be:

14.68 moles of He

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
