Concentration, pH, and molar mass calculators for chemistry students and hobbyists.
Convert between molarity, molality, mass concentration, and mass percentage from the mass of solute, molar mass, solution volume, solvent mass, and solution density.
Convert between hydrogen ion concentration and pH, work out pOH and hydroxide ion concentration, or find the pH of a strong acid or strong base from its concentration.
Apply the dilution law C1V1 = C2V2 to find the volume of stock solution to take, the volume of solvent to add, or the final volume reached from an available stock volume.
Parse a chemical formula such as H2O, NaCl, or Ca(OH)2 and calculate its molar mass from standard IUPAC atomic weights, with a full element by element breakdown.
