The vapor pressure of pure methanol, CH3OH, is 94.0 torr at 20ºC, and the vapor pressure of pure ethanol, CH3CH2OH, is 44.0 torr at the same temperature. If a solution of these two liquids has a total vapor pressure of 65.5 torr at 20ºC, what is the mole fraction of methanol in that solution? (Assume that this is an ideal solution.)

answer: i dont know the answer but this might

explanation:

l

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
