How many atoms of O are there in 1.00 moles of CO2?

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

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
