Question
Chapter 6, Problem 6.43E
Interpretation Introduction
Interpretation:
The boiling point of water in Colorado Springs is to be calculated.
Concept introduction:
The temperature at which the liquid state of a compound changes to the vapour state is termed as boiling point of the substance.
The temperature, at which the liquid boils at a pressure of one atmosphere, is known as normal boiling point.

Mercury is the only metal that is a liquid at room temperature. When mercury vapor is inhaled, it is readily absorbed by the lungs, causing signifiant
health risks. The enthalpy of vaporization of mercury is 59.1 kJ/mol. The normal boiling point of mercury is 357°C. What is the vapor pressure of
mercury at 39°C? Assume the enthalpy of vaporization does not depend on temperature.
