Calculate the boiling point elevation of an aqueous solution of 0.14 m glucose?

Glucose is an covalent compound and doesn't break apart like ionic compounds. so the von hoff factor is only 1
mKfi therefore 0.14 x 1.86= 0.26 lower than the original freezing point

How does freezing point get calculated if boiling point of an aqueous solution is given?
F.p.'s and B.p.'s are independent (intensive) properties, you can NOT calculate them.
How do you separate KNO3 from aqueous sol of KNO3?
It can be separated by boiling off the water or crystallizing the KNO3 from solution
What lowers the freezing point and raises the boiling point?
Yes, it is possible if the solution contain solutes.
How does the boiling point in degrees Celsius of a saltwater solution compare to the boiling point of normal tap water?
The boiling point of salt water will be higher - whichever scale is used to measure the temperature. How much higher will depend on the amount of salt that is dissolved in the water.
What happens to the boiling point of a solution as the concentraion increases?
Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. The boiling point can be measured accurately using an ebullioscope.
Is the boiling point of a 0.5 m aqueous solution of KOH higher than the boiling point of a .5m aqueous solution of KCL?
Colligative properties, such as boiling point elevation, depend on the molality of the solution and the number of "entities" (ions, in this case) per formula unit. For the solutions specified, these are identical, so the answer is no.
What is the freezing point of an aqueous solution if the boiling point of an aqueous solution is 101.34 degree Celsius?
nobody knows

What are some things that are true about boiling points?
The boiling point of 2 m KF in water is 102.4ºC. The boiling point of a 0.5 m aqueous solution of LiOH is the same as the boiling point of a 0.5 m aqueous solution of LiCl.
Compared to the pure water an aqueous solution of calcium chloride has a?
Higher boiling point and a lower freezing point. These are called colligative properties. When a solute is put into solution with the solvent, there is a change in the vapor pressure, osmotic pressure, elevation of the boiling point, and depression of the freezing point.
What is the boiling point elevation of a solution that contains 4.15 moles(mol) solute per kilogram of water?
You need to know the chemical formula of the solute, to obtain the value of the van't Hoff factor, which is included in the formula to calculate the boiling point elevation.
The difference between the boiling point of a liquid in pure state and the boiling point of the liquid in solution?
Boiling Point Elevation
What is the boiling point of an aqueous solution that has a vapor pressure of 18.5 at 25 degrees Celsius?
108.7
What is the boiling point of concentrated aqueous solution of sodium chloride?
104 degree celcius
How do you separate KNO3 from aqueous sol of KNO3?
It can be separated by boiling off the water or crystallizing the KNO3 from solution
Doubling the amount of a nonvolatile solute in a solution?
A. doubles the elevation change of the boiling point
Importance of colligative properties in everyday?
For example the boiling point elevation of a solution containing a dissolved substance.
