The extent of the boiling point elevation can be calculated. It is directly proportional to the molal concentration of the solution. The amount the boiling point is elevated is determined using the equation: \Delta T_b = i \times K_b \times m ΔT b = i ×K b ×m. In this equation,
WebNow, we can use the formula to calculate the boiling point elevation: ΔTb = Kb × molality. ΔTb = 0.512°C/m × 0.892 mol/kg. ΔTb = 0.457°C. The boiling point elevation is 0.457°C. To find the boiling point of the solution, we need to add this to the normal boiling point of water, which is 100°C: WebNov 24, 2024 · Background and Review. A pure substance has a specific boiling point at 1 atm. For water it's 100 degrees Celsius, for ethanol it's 78.4 degrees Celsius.
