POST-LABORATORY QUESTIONS Due after Laboratory Experiment 1. While performing the Dumas experiment, if the outside of the flask were not completely dry (Part I), how would this affect the calculated molar mass of the unknown volatile liquid? Would it be higher or lower? Explain. 2. While determining the pressure during the Dumas experiment, if the barometric pressure reported were lower than the actual vapor pressure (Part I), how would this error affect the calculated molar mass of the unknown volatile liquid? Explain.

Calculate the vapor pressure of propanol (b.p. 97.0 ∘C97.0 ∘C) at the gas chromatography column temperature of 95.0 ∘C95.0 ∘C using the form of the Clausius–Clapeyron equation shown ln(?1?2)=−(Δ?vap?)(1?1−1?2)ln(P1P2)=−(ΔHvapR)(1T1−1T2) where ?R is the ideal gas constant, Δ?vapΔHvap is the enthalpy of vaporization, ?1T1 and ?2T2 are two different temperatures, and ?1P1 and ?2P2 are the vapor pressures at the respective temperatures.
