The vapor pressure of C7H16 at 21.0 Celsius would be [higher/lower] than 400 torr.?

Answer 1

C7H16 is Heptane
Below is the MSDS Sheet for Heptane
Listed under Physical and Chemical Properties
Vapor Pressure (mm Hg): 40 @ 20C (68F)
1 mm Hg= 1 torr

I doubt that an increase of 1 degree C would change the vapor pressure from 40 to + 400
