The molar enthalpy of vaporization of methanol, CH3OH, is 35.2 kJ/mol at 64.6 °C How much energy is required to evaporate 1.00 kg of methanol at 64.6 °C?

Interpretation Introduction

Interpretation:

The energy required to vaporize 1.00 kgof methanol at64.6oC has to be identified.

Concept Introduction:

The energy required to overcome the intermolecular forces of attraction for 1mol of a substance is called standard enthalpy of vaporization,ΔvapH0.

Explanation of Solution

The molar enthalpy of vaporization of methanol is35.2 kJ/mol at64.6oC.

Volume=1Kg =1×103g

  ΔvapH0=+35
