Answer:
Intermolecular forces (IMF) (or secondary forces) are the forces which mediate interaction between atoms, including forces of attraction or repulsion which act between atoms and other types of neighboring particles, e.g. atoms or ions. Intermolecular forces are weak relative to intramolecular forces – the forces which hold a molecule together. For example, the covalent bond, involving sharing electron pairs between atoms, is much stronger than the forces present between neighboring molecules. Both sets of forces are essential parts of force fields frequently used in molecular mechanics.
Explanation:
B) Dalton's law
Explanation:
Dalton's law of total pressure of mixture of gases is the sum of the partial pressure of the gases that makes them up.
The law states that "the total pressure of a mixture of gases is equal to the sum of the partial pressures of the constituent gases".
Pt = P1 + P2 + P3 .....Pn
where:
Pt is the total pressure of gas mixture
P1,P2,P3,...Pn = partial pressure of gases 1,2,3...n respectively
A partial pressure is the pressure a gas would exert if it occupies the volume of a container alone

The solution would be like
this for this specific problem:
<span>(78.6 kJ) / (92.0 g /
(46.0684 g C2H5OH/mol)) = 39.4 kJ/mol </span>
<span>39.3 </span>
So the approximate molar
heat of vaporization of ethanol in kJ/mol is 39.3.
I hope this answers your question.
