At 20 °C the vapor pressure of pure benzene (C6H6) is 75.0 torr, and that of toluene (C7H8) is 22.0 torr. Assume that benzene an
8090 [49]

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

The tetrahedral arrangement of bonds formed by carbon and its relevance In the interaction of biomolecules
Vikentia [17]

Answer:

Due to the presence of 4 valence electrons.

Explanation:

The tetrahedral arrangement of bonds formed by carbon and its relevance In the interaction of biomolecules occurs because the carbon atom has four electrons in their outermost shell and the four hydrogens has one electron each which result is a total of eight electrons distributed in four bonding orbitals making the structure of tetrahedral and the bond angles between these carbon atoms is approximately 109.5 degree.
