What mass percent of sucrose nonelectrolyte present

Reference no: EM13696255

Problem- 1) The boiling point of water at 754 mm hg is 99.78 C. What mass percent of sucrose (c12h22o11 a nonelectrolyte) should be present in order to raise the boiling point to 100.00 C at this pressure? (Kb = .52 C/m)

2) A compound contains only carbon (38.70%), hydrogen (9.74%, and oxygen and is a nonelectrolyte. If 4.34 grams of the compound are dissolved in 25.0 ml of water, the freezing point is found to be -5.20 C. The density of water is 1.00g/ml and Kf= 1.86 C/m. What is the molecular formula of the compound?

If possible please provide me expert solution with complete computation
