Question

A. The normal boiling point of liquid hexane is 342 K. Assuming that its molar heat of vaporization is constant at 30.1 kJ/mol, the boiling point of C₆H₁₄ when the external pressure is 1.25 atm is (Answer in Kelvin)

B.The vapor pressure of liquid iodomethane, CH₃I, is 100. mm Hg at 266 K. A 0.211 g sample of liquid CH₃I is placed in a closed, evacuated 310. mL container at a temperature of 266 K.

Assuming that the temperature remains constant, will all of the liquid evaporate?

What will the pressure in the container be when equilibrium is reached?
