8 g of glucose, C6H12O6 (Molar Mass = 180 g mol−1) is dissolved in 1 kg of water in a sauce pan. At what temperature will this solution boil?

Calculate the boiling point of solution when 4g of MgSO4 (M= 120 g mol-1) was dissolved in 100g of water, assuming MgSO4 undergoes complete ionization. (Kb for water = 0.52 K kgmol-1)
Define the following term:
Molal elevation constant (Kb)
Derive the relation between the elevation of boiling point and molar mass of solute.
Account for the following :
H2S has lower boiling point than H2O.
Calculate the molal elevation constant for water given that 0.2 molal solution of non-volatile and non-electrolyte solute increases the boiling point of water by 0.104 K.
The boiling point to a solution containing 50 gm of a non-volatile solute in 1 kg of solvent is 0.5° higher than that of pure solvent. Determine the molecular mass of the solute (give molecular mass of solvent) = 78 g mol–1 and kb for solvent = 2.53 km–1)
Molal elevation of boiling point constant is the elevation of boiling point produced by ______
Assertion (A): Elevation in boiling point is a colligative property.
