1. What is the mole fraction of each component if 3.9g of benzene C6H6 is dissolved in 4.6g of toluene C7H8?
2.Assuming that this mixture is ideal, (ie.follows Raoult's Law) what is the partial vapor pressure of benezene in this mixture at 50 (C)?
3. Estimate to the nearest degree the temp at which the vapor pressure of the solution equals 1 atm (bp of the solution).
4. Calculate the compostition of the vapor (mole fraction of each component) that is in equilibrium in the solution at the boiling point of this solution.
5. Calculate the composition in weight percentage of the vapor that is in equilibrium with the solution.
