which has the higher boiling point - 0.1M of NaCl or 0.1M glucose

NaCl: Molar mass = 1 * 23 + 1 * 35.5 = 58.5g.

Glucose: C6H12O6 : Molar mass = 6*12 + 12 * 1 + 6 * 16 = 180g

Molarity = Mass of solute/Molar mass of solute * 1000/Volume of solution

Thus, Molarity, molar mass and volume are inversely related. Thus, more is the molarity, less is the BP (ie, volume).

Thus, 0.1M of Glucose has lesser BP.

Nacl has larger boiling point since :

The aqueous NaCl solution has a higher concentration of particles. Moreover The vant hoff factor of Nacl is greater thn 1 while of glucose is 1.
