Answer:

No. of moles of CO in 200 mg = 200 x10-3/28

                                           = 0.0071 mole

No. of molecules in 0.0071 mole of CO = 0.0071 x 6.022 x1023

                                                                =4.28 x 1021 molecules of CO

Since, 1021 molecules are removed, therefore number of molecule remaining are 3.28 x1021
