Transcribed Image Text:**Condensation of Ether**
The following information is provided for ether, \( \text{C}_2\text{H}_5\text{OC}_2\text{H}_5 \), at 1 atm:
- Boiling point = \( 34.6 \, ^\circ\text{C} \)
- \( \Delta H_{\text{vap}}(34.6 \, ^\circ\text{C}) = 26.5 \, \text{kJ/mol} \)
- Specific heat of liquid = \( 2.32 \, \text{J/g}^\circ\text{C} \)
**Problem Statement**
At a pressure of 1 atm, what is \( \Delta H \) in kJ for the process of condensing a 39.4 g sample of gaseous ether at its normal boiling point of \( 34.6 \, ^\circ\text{C} \)?
- Answer input field for \( \Delta H \) in kJ
