Chemical Calculators

Here you can find several useful calculators concerning chemistry:

• Atomic Masses converts amount and mass of elements.
• Molecular Mass calculates the relative mass of a molecule from its chemical formula.
• Atoms Counter counts the number of atoms of each element in one or more chemical formulas.
• Molar Mass convert molar mass, the amount of substance in mol and the mass, calculate the amount of particles.
• Atoms per Mass tells how many atoms are in a certain mass of an element.
• Mass Ratio is a calculator for the ratio of masses of molecules or atoms.
• Mass Fraction and Molar Fraction allows these two parts to be converted into each other using the molar mass..
• Isotopes is a list of every natural and the most important artificial isotopes.
• Neutron-Proton Ratio calculates the numerical ratio of these two nucleons in an atomic nucleus.
• Atomic Nucleus Size provides an estimate of the radius, diameter, and volume of an atomic nucleus.
• Mixing Ratio calculates quantities and percentages of mixtures.
• pH Dilution enables the calculation of pH values of diluted bases and acids.
• Ideal Gas Law calculates pressure, volume, amount or temperature of a gas.
• Gas molecules / V calculates with the Loschmidt constant the number of molecules in an ideal gas per volume.
• Concentration determines the concentration of a substance in a solvent.
• Saline Solution finds out how much salt must be added to water to get a certain concentration.
• Half-life is a calculator for the original and resulting amount of radioactive substances.
• Heat Capacity tells how much energy is needed to warm up certain substances.
• Vaporization is a calculator for the enthalpy of vaporization for liquid water.
• Mix Temperatures gets the temperature of a mix of liquids with different temperatures.
• Mass Units allows the conversion of u, MeV/c², yoctograms and kilograms.
• SI Prefixes converts amounts with prefixes like micro and kilo.

Chemistry is the study of atoms and their compounds, the molecules. It developed from alchemy into a science in its own right during the 18th and 19th centuries. Chemistry is closely linked to physics and often uses methods from mathematics, which are also used in these calculators.
