Henry's law states that the mass of a gas that dissolves in a definite volume of liquid is directly proportional to the pressure of the gas provided the gas does not react with the solvent. William Henry formulated the formula in 1801.
A formula for Henry's Law is:
Taking the natural logarithm of the formula, gives us the more commonly used formula:
- O2 : 4.34×104 atoms
- CO2 : 1.64×103 atoms
- H2 : 7.04×104 atoms
