Calculators list - CHEMISTRY
In this category you'll find calculators, tables and converters related to chemistry. Here you'll find chemical properties of chemical elements and their compounds, convert solution concentration from percent to molar or calculate molar mass of your molecule.
• Converts amount of substance from one unit to another e.g. from milimoles (mmol) to number of particles (atoms or molecules depending on substance) or vice versa.

• Table shows example usage of selected radioisotopes.

• Calculations related to Avogadro's law. Enter known values (e.g. volume or number of moles) and select which value you want to find out (e.g. molar volume) and we'll show you step-by-step how to transform basic formula and reach your result in desired units.

• Tables show length of chemical bonds in selected molecules.

• Calculations related to Clapeyron's equation known also as ideal gas law. Enter known values (e.g. pressure and temperature) and select which value you want to find out (e.g. volume) and we'll show you step-by-step how to transform basic formula and reach your result in desired units.

• Table shows lattice crystal energy in kJ/mol for selected ion compounds.

• Density units converter - converts units between kilograms per cubic meter, grams per liter, ounces per galon etc. Both metric and imperial (US and UK) units are included. Also, you will find more exotic units here, such as multiplicity of Earth density or femtograms per liter.

• Table shows density of selected gases, solids and liquids.

• Converts dimensionless quantity units such as percent, permile, ppm (parts per milion) mU (miliuno) etc.

• Converts dipole moment from one unit to another e.g. from debyes to atomic units or vice versa.

• Table shows values of electric dipole moment of various chemical substances given in any unit you prefer such as debyes, coulomb times meter, atomic units of dipole moment etc.

• Table shows dissociation constants of selected chemical substances in temperature 298K (25°C).

• Table shows overpotential values on selected electrodes.

• Table shows electron affinity (i.e. the amount of energy released when an electron is added to atom) for most of chemical elements.

• Table shows electron configuration of chemical elements in groundstate.

• Table shows basic properties of elementary particles.

• Table shows flame colors specific to given chemical elements such as yellow-orange for sodium (Na), red-cherry for lithium (Li) etc.

• Table shows electrochemical potential of selected elements i.e. so-called galvanic series.

• Table shows ionization energy of chemical elements given in kJ/mol.

• Tables show melting points of various chemical substances. You see name and chemical formula next to temperature converted to the unit of your choice (Celsius deegres, kelvins, Fehrenheits degrees etc.)

• Tables show molar mass of various chemical compounds.

• This calculator converts molar concentration to percentage or vice versa.

• Tables display the volume that one mole of the selected gas occupies.

• Tables show relative permittivity (to vacuum) of various substances (solvents).

• Table shows solubility equilibriums of selected substances, mainly sparingly soluble salts and hydroxides.

• Table shows solubility of various substances under different temperature given in grams of dissoluted substance per 100g of water.

• Table shows solutions color characteristic to given ions (cations or anions) such as Cu2+ (blue) or MNO4- (purple).

• Tables show density of choosen water solutions depending on concentration of dissolved substance at 20 °C.

• Table shows isotopic composition of chemical elements occuring permanently in nature. Isotopes obtained artificially are not presented here.

• Tables show values of standard (1013.25 hPa, 298K) enthalpy of creation (from free elements) of various chemical compounds.

• Tables show values of standard entropy (1013.25hPa, 298K) of various chemical substances.

• Tables show values of standard (1013.25 hPa, 298K) free enthalpy of creation (from free elements) of various chemical compounds.

• Table shows standard potentials of common half-cells at 25 °C.

• Tables show triple points (temperature and pressure) of selected substances i.e. conditions when all three phases (liquid, solid and gas) coexist in thermodynamic equilibrium.

• Convert volume to mass and vice versa. Using this calculator you can check what is the weight of a glass of water or what volume does kilogram of feathers occupy. Use the one of predefined substances (water, steal, wood etc.) or enter custom density in any unit (kg/m3, g/cm3, mg/l etc.)

• Table shows how density of water depends on temperature. Data were measured under so-called normal pressure i.e. 1013,25 hPa.
