You have a solution that contains 19.1 grams of CsH12 and 105.8 g of C6H6. Pure CsH12 has a vapor pressure of 425 torr at 298 K while pure C6H6 has a vapor pressure of 91.1 torr at 298 K. What is the vapor pressure (in torr) of the solution at 298 K? Molar masses: CsH12 = 72.14 g/mol C6H6 78.11 g/mol 5) You dissolve 304.5 g of an unknown solute into 814.6 g of CH3CH₂OH. The solution boils at 81.33 °C. You know from other data that the solute is a weak acid where 14.6% of the molecules will dissociate into cation and anion. What is the molar mass of the unknown solute? Pure CH₂CH₂OH boils at 78.31°C with a Ks = 1.22 °C/m. Pure CH-CH₂OH freezes at -114.18°C with a KF = 1.99 °C/m The molar mass of CH3CH₂OH is 46.07 g/mol. The density of CH₂CH₂OH liquid is 0.789 g/mL. The density of the solution is 0.803 g/mL...
