WILL MARK U BRAINLIEST. How many atoms of oxygen are found in one mole of naturally occurring oxygen gas (O2)? Is this different from the number of atoms found in one mole of pure solid iron? Be sure to explain your answer using reference to Avogadro's number.

The atomic mass of each element is listed below the symbol of the element in the periodic table: Cu =

63.55 amu, Hg = 200.59 amu, S = 32.07 amu, and He = 4.00 amu. The mass of Avogadro’s number of atoms

is the atomic mass expressed in grams. Therefore, 6.02 × 1023 a
