Answer:
1.204 x 10²⁴ atoms of oxygen in 1 mole of CO₂
Explanation:
1 mole of CO₂ contains 6.02 x 10²³ molecules of CO₂
1 molecule of CO₂ contains 2 atoms of oxygen
Therefore, Atoms of oxygen in 1 mole of CO2 => 6.02 x 10²³ molecules CO₂ x
2 atoms oxygen / molecule CO₂ = 2 X 6.02 X10²³ atoms of oxygen = 1.204x10²⁴ atoms of oxygen in 1 mole CO₂
