To calculate the partition coefficient in a given system, you divide the concentration of a substance in one phase by the concentration of the same substance in another phase. This helps determine how a substance distributes between two phases, such as between a solvent and a solute.

To calculate the diffusion coefficient in a system, one can use the equation D (2RT)/(6r), where D is the diffusion coefficient, R is the gas constant, T is the temperature, is the viscosity of the medium, and r is the radius of the diffusing particle. This equation is derived from the Stokes-Einstein equation and is commonly used in physics and chemistry to determine diffusion coefficients.
Diffusion in a system can be calculated using Fick's law of diffusion, which states that the rate of diffusion is proportional to the concentration gradient. The formula for calculating diffusion is D (C2 - C1) / (X2 - X1), where D is the diffusion coefficient, C is the concentration, and X is the distance.
To calculate the mole fraction from pressure in a given system, you can use the formula: Mole fraction Partial pressure of the component / Total pressure of the system Simply divide the partial pressure of the component by the total pressure of the system to find the mole fraction.
The evaporation equation used to calculate the rate of water loss is: Evaporation Rate (Surface Area) x (Evaporation Coefficient) x (Temperature Difference) x (Wind Speed)
The formula to calculate the number of angular nodes in a system is n-1-l, where n is the principal quantum number and l is the azimuthal quantum number.
