A formula for Henry's Law is:
where P is the partial pressure of the gaseous solute above the solution, C is the concentration of the gas in mol/L and k is the Henry's Law constant[?], which has the units L*atm/mol.
Taking the natural logarithm of the formula, gives us the more commonly used formula:
This version is used to showcase the effectiveness of the law for dilute solutions of gases that don't react with the solvent. Some values for k include:
when these gases are dissolved in water at 299 Kelvins
