Interpretation: The amount of heat absorbed when a certain amount of chloroethane vaporizes at its normal boiling point.
Concept Introduction: The molar enthalpy of vaporization is the amount of energy that must be added to 1 mole of liquid substance to transform it into vapor at its normal boiling point.
Answer to Problem 25SP
The amount of heat absorbed when
Explanation of Solution
The molar heat of vaporization of chloroethane at
This means to convert
Amount of chloroethane
Moles of substance is calculated by dividing the amount of substance by the molar mass of the substance.
Moles of chloroethane =
Thus,
