hope it helps!!

Answer 2

Answer:

7.78128

Explanation:

Mole of oxygen atoms = 3.011 × 10^24

Number of moles of oxygen atoms = 2.58×10^24/3.011×1024

2.58 × 10000000000000000000000000/3.016 × 1000000000000000000000000

( 10000000000000000000000000)/( 10000000000000000000000000) WILL Be cancelled

then the number left is (2.58/3.011)

divide 2.58 with 3.011

so, therefore answer is: (7.78128)

I hope my answer is right and it has helped you
