a liquid bas a AHvap of 30.4kJ/mol and a boiling point of 128.0 °c at 1.00atm what is its vapor pressure ar 104.0°c? be sure your answer has the correct number of significant figures
A liquid has a \( \Delta H_{\text {vop }}^{\circ} 30.4 \frac{\mathrm{kJ}}{\mathrm{mol}} \) and a boiling point of \( 128.0^{\circ} \mathrm{C} \) at \( 1.00 \mathrm{~atm} \). What is its vapor pressure at \( 104.0^{\circ} \mathrm{C} \) B Be sure your answer has the correct number of significant figures. Note: Reference the Fundamental constants table for additional information.
Expert Answer
Solution:- It is known that pressure and temperature are non-linearly proportional. By knowing the heat of vaporisation of a substance, the vapour pre
