Chemistry

Molar mass, molarity, dilution, pH, the ideal gas law and equation balancing.

• Molar Mass CalculatorType any chemical formula, with brackets or water of crystallisation, and get the molar mass and the mass percent of every element.
• Mole, Gram and Particle ConverterConvert between grams, moles and the number of particles (molecules or atoms) of any substance just by typing its chemical formula.
• Molarity CalculatorCalculate molarity, the mass of solute needed to prepare a solution, or the volume of solution a known mass makes.
• Dilution Calculator (C1V1 = C2V2)Solve any unknown in the dilution equation C1V1 = C2V2, with the volume of solvent to add to the stock solution.
• pH CalculatorConvert between pH, pOH and the hydrogen [H+] and hydroxide [OH-] ion concentrations at 25 °C, with the nature of the solution.
• Ideal Gas Law CalculatorSolve for pressure, volume, moles or temperature with the ideal gas equation PV = nRT, in the units you choose.
• Chemical Equation BalancerType an unbalanced chemical equation and get the correct coefficients automatically by solving the element matrix.
