Please Help and explain like your explaing to a child. Thanks!

The dark grey is the answer but I don't understand.

igative properties 6) Given our sugared iced (T=5C) tea, which is mostly water and sugar, if I dissolved 20g of sugar in 125g"tea" which might as well be water; a) Calculate the vapor pressure of the tea solution P=XsugarP1(solvent) At 5C, the vapor pressure of pure water is.....see table 5.3, then multiply by the mole fraction of sugar to find by how much the vapor pressure of water is lowered, and subtract from the pure VP of water at that temperature. Ans: 6.38mmHg b) Calculate the boiling point of the tea solution? Tb=iKbm Find the boiling point elevation constant for water in the textbook, then multiply by the molality of the sugar solution. i is the van't Hoff factor... which is what for sucrose... Since it is a boiling point elevation add the Tb to the BP of the pure water. New BP =100.24C c) The boiling point of a solution is altered by the presence of dissolved particles. Arrange the following aqueous solutions in order of increasing boiling points: 0.300mC6H12O6,0.110m K2CO3, and 0.050mAl(ClO4)3 Explain. Since the greater the concentration of particles the greater the boiling point elevation. To find the molality of the particles, multiply the molality of the solution by the number of particles, which provides the actual molality of the particles affecting the boiling point. 0.050mAl(ClO4)3
