How many moles are in 2.71 molecules of carbon dioxide (CO2)

This has already been answered but here is the

2.71×10 molecules of co2 * 1 Mole CO2 /6.022 *10^23 molecules of CO2

= 4.5*10^-14 Mole  CO2

1 mole of CO2 has 2 mole oxygen  

4.5*10^-14 Mole  CO2 *2/1

= 9.0*10^-14 Mole oxygen  

i would say b

explanation:

but i think i would need more information than that
