Answer:
Option E is correct. 320K
Explanations:
In order to get the normal boiling point of the liquid, we will use the Clausius-Clapeyron equation expressed according to the equation:
where:
P1 is the vapor pressure of that substance at T1
P2 is the vapor pressure of that substance at T2
ΔHvap is the enthalpy of vaporization.
R is the gas constant - usually expressed as 8.314J/Kmol
Given the following parameters:
Substitute the given parameters into the formula to get T2
Simplify the result to get the value of T2
Hence the normal boiling point of this liquid is approximately 320K
