You are in a mountain range with atmospheric air pressure of 520 mmHg , and you wish to boil some eggs. What is the approximate boiling point of the water at this air pressure?

Look up the vapor pressure of H2O at various temperatuares. I assume you have a table in your text/notes; otherwise, you can look on the web. Look for a vapor pressure of 520 mm and the temperature that produces that will be the boiling point. WHY? Because boiling point is defined as the temperature at which the vapor pressure of a liquid is the same as atmospheric pressure.
is there any formula that I can use to find out the vapor pressure at a certain temperature without using the table?
Is there a formula used to calculate this problem, or should I only look at the table in my book?
