Chemists often work at reduced pressures so that solvents can be removed at lower temperatures. Toluene which has a normal boiling point of 110.6 °C is one such solvent. What is the boiling point temperature of toluene at a reduced pressure of 1.00 mm Hg? (ΔvapH° for toluene = 38.1 kJ/mol and R = 8.314 J/K⋅mol)
