The vapour pressure of ethanol is math xmlns=http://www.w3.org/1998/Math/MathML class=wrs_chemistrymn115/mn/math torr at \( 34.9^{\circ} \mathrm{C} \). if \( \Delta \mathrm{H}_{\mathrm{vap}} \) of ethanol is \( 38.6 \mathrm{~kJ} / \mathrm{mol} \). Calculate the temp. \( \left({ }^{\circ} \mathrm{C}\right) \) when then vapour pressure is math xmlns=http://www.w3.org/1998/Math/MathML class=wrs_chemistrymn760/mn/math torr.
