A polystyrene,having the formula Br3C6H3(C3H8)n,contains 10.46% bromine by weight,find the value of n A polystyrene,having the formula Br3C6H3(C3H8)n,contains 10.46% bromine by weight,find the value of n
Br3 molecular weight = 240Br3C6H3 weight = 315C8H8 = 104Molecular weight of whole compound would be=> 315 + 104n% Br = 240/(315 + 104n) * 100 => 10.46%On solving,we get n = 19 approx.
