Question

hexane is a nonpolar liquid. the vapor pressure of hexane at its normal boiling point is ________. a = 1 atm b not enough information c > 1 atm d < 1 atm

Explanation:

The normal boiling point of a liquid is defined as the temperature at which its vapor pressure equals the external pressure. By convention, the normal boiling point is measured at an external pressure of 1 atm. So, at the normal boiling point, the vapor pressure of the liquid (hexane in this case) must equal 1 atm.

Answer:

A. = 1 atm
