When 100gm Ethene polymerises entirely to poly ethene, the weight of poly ethene formed as per the equation nCH_3 = CH_2 to (CH_2- CH_2)_n is

Answer»

`(n)/(2) g`
`100G `
`(100)/(n)g`
`100 ng `

Solution :Moles of Ethene ` XX 2`
= Moles of POLY Ethene ` xx n xx 2 `
`(100)/(28) xx 2 = ("weight of poly ethene ")/(28 xx n) xx n xx 2`
Weight of poly ethene = 100g
