Formula: H 3 O 4 P. Molecular weight: 97.9952. IUPAC Standard InChI: InChI=1S/H3O4P/c1-5 (2,3)4/h (H3,1,2,3,4) IUPAC Standard InChIKey: NBIIXXVUZAFLBC-UHFFFAOYSA-N. CAS Registry Number: 7664-38-2. Chemical structure: This structure is also available as a 2d Mol file or as a computed 3d SD file.
The calculator uses the Clausius-Clapeyron equation to compute the boiling point. This equation illustrates the relationship between pressure and temperature for phase transitions. By knowing the heat of vaporization and the boiling point at standard pressure, the calculator can predict how the boiling point changes with pressure.
