Two moles of sucrose are dissolved in eight moles of water. Assume that the solution follows Raoult's Law, but that the vapor pressure of sucrose is negligible, as it is for most solids. The distillation is carried out at 1 atm.
a) The vapor pressure of the solution at 100 degrees celsius is 0.8atm.
b) What temperature is observed at the still-head thermometer during this entire distillation?
