Question

The concentration of sugars ina maple syrup is about 66 g per 1 L Estimate the boiling point (Kb for water (~0.51 oC/m) of such a sugar solution. Use molecular weight of sucrose (C22O11 H22, 342g mol ) in your calculations, and assume that the weight of 1 L of syrup equals to 1000 Select one: a. 100.1°C b. 110°C c. 101.1°C d. 101°C

Answer 1

To (solution) - To (Solvent) = Kgb bis molality b= MASS OF SuckOSE MW OF SUCKOSE MASS OF SOLVENT (kg) MASS OF = 1000g - 669 = 9348 i ba = 934gx 0.001 kg = 0.934 kg 669 342 g moet = 0.207 mol/kg 01934 kg i Te (solenou) – 100°c = 0.57°c kok x 0.207 meter Te (soluriow) = ( 100.1°C
