02 will be the same as in the number of molecules in Options are 28g of Co,14g of CO,7 g of CO, 11g of NO2​

Answer 1

Answer:

7g of CO

Explanation:

No.of molecules in 8g of O2=No.of moles*Avagadro's no.(A)

                                           =(8/32)*A

                                            =1/4*(A)
