Solutions, molarity & reactions

• Molarity CalculatorCalculate molarity, moles or volume of a solution from the other two — with built-in molar mass lookup for common compounds.
• Solution Dilution CalculatorUse C₁V₁ = C₂V₂ to find the stock volume or final concentration for any solution dilution.
• pH CalculatorFind the pH of a solution from its hydrogen ion concentration — plus pOH, hydroxide concentration, and acid/base classification.
• Percent Yield CalculatorCompare actual yield to theoretical yield to get reaction efficiency, with the gap expressed in grams and percent.
• Molecular Weight CalculatorEnter a chemical formula like CuSO4*5H2O or Ca(OH)2 to get its molar mass, plus the mass of a custom sample in grams.
• Ideal Gas Law CalculatorSolve PV = nRT for any variable — pressure, volume, moles, or temperature — with the other three held constant.
• Half-Life CalculatorEnter an initial amount, half-life, and elapsed time to see what remains — plus the decay constant and mean lifetime.
