Question

If you have 3 moles of CO₂, how many atoms of Oxygen (0) do you have

Answer 1

Answer: 3.61 x 10*24 O atoms.

-Explanation -

1 molecule of CO2 equals 1 C atom + 2 O atom.

1 mole of CO2 equals 6.02 x 10*23 CO2 molecules

Therefore , 1 mole of CO2 contains (2 x 6.02 x 10*23) O atoms, which means that 3 moles of CO2 contains (3 x 2 x 6.02 x 10*23) O atoms
