Question
The vapor pressure at 20 °C of pure hexane is 120. torr, and pure 2-methyl pentane is 172 torr. Determine the vapor pressure (torr) of hexane in a mixture of 24.0 g of hexane and 44.0 g of 2-methyl pentane. The molar mass of both hexane and 2-methyl pentane is 86.0 g/mol.
Expert Solution
Step 1
Given, mass of hexane = 24.0 g
Mass of 2-methyl pentane = 44.0 g
Vapour pressure of pure hexane , p° = 120 torrr
Molar mass of Hexane = 86.0 g/mol
Vapour pressure of Hexane in mixture = ?
