Fluorocarbon polymers can be made by florinating polyethylene according to the reaction
`2CoF_(2)+F_(2)rarr2CoF_(3)`
`(CH_(2))_(n)+4nCoF_(3)rarr(CF_(2))_(n)+2nHF +4nCoF_(2)`
The `CoF_(3)` can be regenerated by the reaction
`2CoF_(2)+F_(2)rarr2CoF_(3)`
Calculate kg of fluorine consumed per kg of fluorocarbon produced `(CF_(2))_(n)`
[Write the answer excluding the decimal places]
