ボイルの法則
These are analogous to Boyle's law and Charles's Law for gases. Similarly, the combined ideal gas law, formula_18, has as analog for ideal solutions formula_19, where formula_20 is osmotic pressure; V is the volume; n is the number of moles of solute; R is the molar gas constant 8.314 J K−1 mol−1; T is absolute temperature; and "i" is the Van 't Hoff factor.
