. a). Find the mass of nonelectrolyte solute dissolved in 315 g water with boiling point temperature of 100.45 ⁰C. The molar mass of solute is 46 g/mole Kb = 0.52 ⁰C/m and Tb = 100 ⁰C
100.45×315/100×0.52= 608.5g

100ml ,1 M OF sucrose solution when treated with charcol becomes 0.8M .Amount of sucrose adsorbed in moles is ?
100 mL = 0.1 LInitial amount in moles:1mol/L * 0.1L = 0.1 molFinal amount in moles:0.8mol/L * 0.1L = 0.08 molTherefore, the amount of sucrose adsorbed is 0.1 - 0.08...

What mass of sucrose (C 12 H 22 O 11 ) is dissolved in 50.0 mL of a 0.400 mol/L solution of
sucrose in water?
n(C12H22O11) = V*C = 0.050*0.400 = 0.02 molm(C12H22O11) = m*M = 0.02*342 = 6.84 g

At what temperature will a sucrose solution boil if it contains 1.55 moles of sucrose in 600mL of water? kb of water is 0.51°C/m.
∆T=Kb×m, where m is molality (number of moles of solute per kilogramme of solvent).If the density of water is 1g/ml, 600 ml weights 600 g or 0.6 kg.Molality equals tom=1.55/0.6=2.58(mol/kg)∆T=T-T0,...

What is the vapor pressure of a 1.00 molal sugar solution at 25°C? Sugar is a nonvolatile, nonelectrolyte solute. The vapor pressure of water at 25°C is 23.8 torr.
[Psaturated(water)-P(water)]/Psaturated(water)=1-xwater=xsugar, x is the mole fraction1 molal solution => 1 mol of sugar and 1 kg of water => 1 mol of sugar and 1000/18.015=55.402 mol of water => xsugar...
