Web29 dec. 2024 · Henry's law provides a basis to determine the solubility of gases in liquids. Henry found that at a constant temperature, the concentration of a soluble or semi-soluble gas in a liquid was proportional to the partial pressure of the gas that is in equilibrium with the liquid. The proportionality constant is known as the Henry's law constant (HLC). WebTo use Henry’s Law on a water concentration in µg/L, you would first convert to parts per billion by volume (ppb v), by dividing by the Molecular Weight of PCE (165.83 g/mol), and then covert back to µg/L in gas by multiplying by the Molecular Weight — the molecular Weight Calculations to ppbv and from ppb cancel out. ch 2 tulsa weather radar
