SUMMARY
The molal concentration of pure ether can be calculated using the formula ΔTb = Kb * m, where Kb for ether is 2.02. The normal boiling point of pure ether is 37 degrees Celsius. To find the molal concentration (m), one must first determine the change in boiling point (ΔTb) of the solution. Without knowing the boiling point of the mixture, accurate calculation of the boiling point elevation and, consequently, the molal concentration is impossible.
