133 grams of Propanol (CH3CH₂CH₂OH) condenses from liquid to solid at its freezing point. How much energy is removed (in kJ)? Note: 'energy removed' means it is asking for the 'quantity' of energy not if it is - or +. Information that you may or may not need: AHfus (propanol) = 5.20 kJ/mol. AHvap (propanol) = 41.4 kJ/mol Molar Mass of propanol = 60.09 g/mol Answer Format Record your answer to three significant figures.
