Answer

The mass percent of acrylonitrile is $16.90 %_$ .

The mass percent of butadiene is $17.22 %_$ .

The mass percent of styrene is $33.18 %_$ .

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 $0.605 g$ .

The mass of ABS plastic is $1.20 g$ .

The molar mass of bromine is $158 g/mol$ .

The number of moles is calculated by the formula,

$Number of moles=Given massMolar mass$

Substitute the given value of the mass and molar mass of bromine in the above expression.

$Number of moles of bromine=Given massMolar mass=0.605 g158g/mol=0.003829mol$

Hence, each molecule in this polymer contains $0.003829mol$ .

Therefore, $0.003829mol$ of bromine reacted with $0.003829mol$ of polymer.

The ABS plastic is constructed by equimolar ratio of the three molecules. Hence, each molecule is $0.003829mol$ .

The mass of acrylonitrile, styrene and butadiene is calculated as,

The molar mass of acrylonitrile is $53 g/mol$ .

The molar mass of butadiene is $54 g/mol$ .

The molar mass of styrene is $104 g/mol$ .

The mass of acrylonitrile, styrene and butadiene is calculated by using the formula,

$Mass=Number of moles×Molar mass$ .

Substitute the given value of the number of moles and molar mass of in the above expression.

For acrylonitrile,

$Mass of acrylonitrile=Number of moles×Molar mass=0.003829 mol×53 g/mol=0.2029 g$

For butadiene,

$Mass of butadiene=Number of moles×Molar mass=0.003829 mol×54 g/mol=0.2067 g$

For styrene

$Mass of styrene=Number of moles×Molar mass=0.003829 mol×104 g/mol=0.3982 g$

Therefore,

The molar mass of acrylonitrile is $53 g/mol$ .

The molar mass of butadiene is $54 g/mol$ .

The molar mass of styrene is $104 g/mol$ .

The mass of acrylonitrile, styrene and butadiene is calculated by using the formula,

$Mass=Number of moles×Molar mass$ .

Substitute the given value of the number of moles and molar mass of in the above expression.

For acrylonitrile,

$Mass of acrylonitrile=Number of moles×Molar mass=0.003829 mol×53 g/mol=0.2029 g$

The molar mass of acrylonitrile is $53 g/mol$ .

The molar mass of butadiene is $54 g/mol$ .

The molar mass of styrene is $104 g/mol$ .

The mass of acrylonitrile, styrene and butadiene is calculated by using the formula,

$Mass=Number of moles×Molar mass$ .

Substitute the given value of the number of moles and molar mass of in the above expression.

For acrylonitrile,

$Mass of acrylonitrile=Number of moles×Molar mass=0.003829 mol×53 g/mol=0.2029 g$

Answer to Problem 154CP

Answer

The mass percent of acrylonitrile is $16.90 %_$ .

The mass percent of butadiene is $17.22 %_$ .

The mass percent of styrene is $33.18 %_$ .

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 $0.605 g$ .

The mass of ABS plastic is $1.20 g$ .

The molar mass of bromine is $158 g/mol$ .

The number of moles is calculated by the formula,

$Number of moles=Given massMolar mass$

Substitute the given value of the mass and molar mass of bromine in the above expression.

$Number of moles of bromine=Given massMolar mass=0.605 g158g/mol=0.003829mol$

Hence, each molecule in this polymer contains $0.003829mol$ .

Therefore, $0.003829mol$ of bromine reacted with $0.003829mol$ of polymer.

The ABS plastic is constructed by equimolar ratio of the three molecules. Hence, each molecule is $0.003829mol$ .

Therefore,

The mass of acrylonitrile, styrene and butadiene is calculated as,

The molar mass of acrylonitrile is $53 g/mol$ .

The molar mass of butadiene is $54 g/mol$ .

The molar mass of styrene is $104 g/mol$ .

The mass of acrylonitrile, styrene and butadiene is calculated by using the formula,

$Mass=Number of moles×Molar mass$ .

Substitute the given value of the number of moles and molar mass of in the above expression.

For acrylonitrile,

$Mass of acrylonitrile=Number of moles×Molar mass=0.003829 mol×53 g/mol=0.2029 g$

For butadiene,

$Mass of butadiene=Number of moles×Molar mass=0.003829 mol×54 g/mol=0.2067 g$

For styrene

$Mass of styrene=Number of moles×Molar mass=0.003829 mol×104 g/mol=0.3982 g$

Therefore,

Mass percent of acrylonitrile, styrene and butadiene is calculated as,

For acrylonitrile,

$Mass percent of acrylonitrile = 0.20291.20×100= 16.90 %_$

For butadiene,

$Mass percent of butadiene = 0.20671.20×100= 17.22 %_$

For styrene

$Mass percent of styrene = 0.39821.20×100= 33.18 %_$
