Use C₁V₁ = C₂V₂ for an ideal dilution where the amount of solute is conserved.
Fill two fields and leave the one you want to calculate empty.
To prepare 100 mL at 0.10 mol/L from a 1.0 mol/L stock, use 10 mL of stock and dilute to a final volume of 100 mL.
118 elements. One clear map of matter. Explore the periodic table, open any element, or jump straight into scientific converters.
Dmitri Mendeleev arranged the known elements so that recurring chemical properties became visible. He deliberately left gaps where the pattern suggested undiscovered elements should exist. That idea — structure before completeness — still makes the periodic table one of science’s most powerful maps.
Everyday scientific phenomena explained with living diagrams and concise, carefully checked text. The motion helps show the mechanism; the article explains what the diagram simplifies.
Evaporation is the passage of molecules from the surface of a liquid into the gas phase. Water does not need to boil for this to happen.
