Answer:
6 x 10^24 O2 atoms
Explanation:
Moles of O2 = 5.00 mol
Number of atoms = number of moles x (6.02 x 10^23 O2 atoms / 1 mol) x (2 O atoms / 1 O2 Molecule )
= 5 mole 02 (6.02 x 10^23 O2 x 2) / (1 mole O2 )
= 6 x 10^24 O2 atoms
5 moles of oxygen contains 6.02×10²⁴ 6.02×10²⁴atoms of oxygen.
We know that one mole of any element or compound contains 6.02×10²³ atoms or molecules.
So one mole of Oxygen molecule (O₂) also contains 6.02×10²³ O₂ molecules.
Now 1 molecule of O₂ contains 2 atoms of oxygen.
Thus, 1 mole of Oxygen molecule (O₂) contains 2×6.02×10²³ atoms of oxygen.
Therefore, 5 moles of oxygen contains:
N = 5×2×6.02×10²³ atoms
N = 6.02×10²⁴ atoms of oxygen.
