JEE MainChemistryModerateMole concept
When 100g of ethylene polymerises entirely to polyethene, the
weight of polyethene formed as per the equation [IMAGE] is
Show answer and solution
By applying POAC for C atoms
moles of ethylene × 2 = mole of polythene × n × 2
[IMAGE] wt. of polyethene = 100 g
moles of ethylene × 2 = mole of polythene × n × 2
[IMAGE] wt. of polyethene = 100 g
