A solution is prepared by dissolving 396 g of sucrose (C12H22O11) in 624 g of water. What is the vapor pressure of this solution at 30°c? The vapor pressure of water is 31.8 mmHg at 30°c
Psolution=(0.9677×31.8mmHg)P_{solution} =(0.9677×31.8mmHg)Psolution=(0.9677×31.8mmHg)
Psolution=30.8mmHgP_{solution} =30.8mmHgPsolution=30.8mmHg
XSolvent=34.63588mol1.156+34.635X_{Solvent} =\frac{34.63588mol}{1.156+34.635}XSolvent=1.156+34.63534.63588mol
XSolvent=0.9676781X_{Solvent} =0.9676781XSolvent=0.9676781
