What is the boiling point of cyclohexane at 620 mmhg? can you show calculations?

Boiling point of cyclohexane at 620 mm Hg is 440.6 K

Explanation:

According to clausius-clapeyron equation for a liquid-vapour equilibrium-

where and are vapor pressure of liquid at and temperature respectively

is the molar enthalpy of vaporization of liquid

Let's assume is equal to standard molar enthalpy of vaporization of a liquid

For cyclohexane, standard molar enthalpy of vaporization is 32.83 kJ/mol

Here, = 620 mm Hg, is 450.8 K (boiling point of cyclohexane) and is 760 mm Hg

So,

So,
