Chemistry Calculators

Chemistry is the Science of Matter where you learn about a matter’s composition & properties. How a matter is formed and what happens when it reacts with another matter or substance. This online tool of Chemistry calculator will help you to solve equations and problems related to Acid-Base Reactions, Buffers, Catalysis, Chemical Equilibrium, Empirical and Molecular Formulas, Electrochemistry, Electrolysis, Electron Quantum Numbers, Gas Laws (Ideal, Dalton’s and Graham’s Law), Ionic/Covalent Bonds, Ions and Molecules, Kinetics, Mass Spectrometry, Nuclear decay, Oxidation-Reduction Reactions, Percentage Composition, Significant Figures & Solution Concentration. Whether you need to calculate the pKa of a solution or just a pH, use WebQC pH calculator to find out. Use the formula of Activation Energy to know a reaction’s activation energy in J/mol instead of Btu/lb mol.

Practise This Question

The resistance a solution A is 50 ohm and that of solution B is 100 ohm, both solutions are taken in the same conductivity cell. If equal volumes of solution A and B are mixed, what is the resistance of the mixture using the same cell? (Assume there is no change or increase in the α of A and B on mixing)
