An alkene monomer has the molecular formula C8H16\text{C}_8\text{H}_{16}C8H16.
The table shows three proposed descriptions of the polymer made from this monomer.
| Report | Formula of one repeating unit | Bond between the two carbon atoms that were joined by the double bond in the monomer |
|---|---|---|
| A | C8H16\text{C}_8\text{H}_{16}C8H16 | double bond |
| B | C8H14\text{C}_8\text{H}_{14}C8H14 | single bond |
| C | C8H16\text{C}_8\text{H}_{16}C8H16 | single bond |
Explain which report is consistent with addition polymerisation.
One molecule of the polymer contains 19 200 atoms in total.
Calculate the number of alkene molecules that joined to make this polymer molecule.
