Answer:
The answer to your question is: P2 = 846 kPa
Explanation:
Data
V1 = 2.5 l
P1 = 300 kPa
T1 = 273 °K
P2 = ?
V2 = 1 l
T2 = 308°K
Formula
P2 = 846 kPa
Answer:
mole fraction benzene = 0.62
mole fraction toluene = 0.38
Explanation:
Raoults law for ideal solutions tells us that the totoal vapor pressure of the solution will be given by adding the partial pressures of the components of the solution and the partial pressures are simply given by the product of the component in solution times its pure vapor pressure at the temperature given:
<h2>p total = x₁ P⁰₁ + x₂ P⁰₂</h2>
where x1 and x2 for this solution denote the mole fractions of benzene and toluene and p⁰ ₁, p⁰₂ the vapor pressures of benzene and toluene respectively.
Solving the algebraic equation:
75 x₁ + 22 x₂ = 55
75 x₁ + 22 ( 1- x₁) = 55 (since x₁ + x₂ = 1)
75 x₁ + 22 - 22 x₁ = 55
53 x₁ = 33
x₁ = 0.62
x₂ = 1 - 0.62 = 0.38

Polymers are the molecular structure in which the larger number of small units are bond together.
Explanation:
The polymer are composed of hydrocarbon the components of carbon and hydrogen. The polymers are resistant to chemiclas, they act as both thermal and electrical insulators, they can be processed in various ways usually made up of petroleum. polymers are used to make items that have no alternatives from other material.
They have covalent bonds that holds the atoms in the polymer molecules together and secondary bonds that holds group of polymer chains together to form the polymeric material.
Diamond and graphite are polymers.
Carbon dioxide is a molecule with molecular formula CO2 and it is made up of two oxygen atoms and covalently bonded with one carbon atom.
PLA is a type of condensation polymer. Hydroxyl group of one lactic acid reacts with carboxylic group of second lactic acid and a ester is formed with the elimination of water molecule. And the reaction propagates with the increase in chain. And, the product formed is PLA as shown below.
