Malachi Estrada · Answer 1

142.0mol CO2

Explanation:

To convert from molecules to moles we must divide the amount of molecules by Avagadro's number, 6.02 x 10^23.

8.551 x 10^25 / 6.02 x 10^23 = 142.0mol CO2

Aditya Melton · Answer 2

moles = no. of molecules / avagardo number

=8.511*10^25 / 6.022*10^23

=14.13 moles
