Because Na3PO4 . = 141.98 g/mol) that has been dissolved in a 250 mL volumetric flask and diluted to the mark. Experimentally, we know that the change in boiling point of the solvent above a solution from that of the pure solvent is directly proportional to the molal concentration of the solute: T is the change in boiling point of the solvent, Because strong acids are essentially 100% ionized, the concentration of the acid in the denominator is nearly zero and theKavalue approaches infinity.
