Assuming 100% polymerization of an organic compound in is aqueous solution, te number of moles of orgaic compound undergoing polymerization containing 9.4g of organic compound per 100g of the solvent is ……….Freezing point depression is 0.93K, K_(f) of water is 1.86K kg"mol"^(-1) and molecular weight of organic compound is 94u

Answer»


SOLUTION :Assume organic compound is `A` and `n` MOLECULES of A POLYMERISE
`DeltaT_(f)=iK_(f)m`
`i=(DeltaT_(f))/(K_(f)m)=(0.93xx94xx100)/(1.86xx9.4xx1000)`
`i=1/n=0.5`
`n=2`
