Concept introduction: The polymers (repeating structural units) are derived from the simple and reactive molecules, called as monomers. ABS plastic is a terpolymer of styrene, acrylonitrile and polybutadiene.
To determine: The percent by mass of acrylonitrile, butadiene and styrene in the polymer sample.
(b)

Answer to Problem 154CP
Answer
The mass percent of acrylonitrile is
The mass percent of butadiene is
The mass percent of styrene is
Explanation of Solution
Explanation
The mass percent of the three given monomers is calculated below.
Given
The mass of bromine to react completely with ABS plastic is
The mass of ABS plastic is
The molar mass of bromine is
The number of moles is calculated by the formula,
Substitute the given value of the mass and molar mass of bromine in the above expression.
Hence, each molecule in this polymer contains
Therefore,
The ABS plastic is constructed by equimolar ratio of the three molecules. Hence, each molecule is
Therefore,
The mass of acrylonitrile, styrene and butadiene is calculated as,
The molar mass of acrylonitrile is
The molar mass of butadiene is
The molar mass of styrene is
The mass of acrylonitrile, styrene and butadiene is calculated by using the formula,
Substitute the given value of the number of moles and molar mass of in the above expression.
For acrylonitrile,
For butadiene,
For styrene
Therefore,
Mass percent of acrylonitrile, styrene and butadiene is calculated as,
For acrylonitrile,
For butadiene,
For styrene
