Calculators

Calculates the molarity of an unknown solution using titration data.

Calculates the estimated Total Dissolved Solids (TDS) in water based on Electrical Conductivity (EC). TDS represents the total concentration of dissolved substances in water, typically expressed in parts per million (ppm) or milligrams per liter (mg/L).

Calculates the volume of stock solution needed to create a diluted solution of a desired concentration and volume using the formula C1V1 = C2V2.

Calculates the saponification value of a fat or oil, which represents the amount of base (typically KOH) required to saponify 1 gram of fat. This value is crucial in soap making and lipid analysis.

Calculates the required volume of diluent to add to a dry ingredient (drug) to achieve a desired concentration, and the resulting mass of the drug in a given volume.

Calculates the required amount of each substance in a mixture based on a given mixing ratio and total desired amount.

Calculates the vapor pressure of an ideal solution using Raoult's Law. It can also determine the vapor pressure and mole fraction of a pure solvent in a solution.

Calculates the pH of a solution based on hydrogen ion concentration ([H+]), or the acid dissociation constant (Ka) and solution concentration.

Calculates the mass/volume percent, mass percent, and volume percent of a solution.

Converts percentage concentration of a solution to molarity, given the density and molecular weight of the solute.
