molekyylimäärän
Molekyylimäärän, often translated as molar amount or amount of substance, is a fundamental concept in chemistry. It quantifies the number of elementary entities, such as atoms, molecules, ions, or electrons, present in a given sample. The standard unit for molekyylimäärä is the mole (mol).
The mole is defined based on Avogadro's number, which is approximately 6.022 x 10^23. This means that
Understanding molekyylimäärä is crucial for stoichiometric calculations, which involve determining the relative amounts of reactants and
To determine the molekyylimäärä of a substance, one typically uses its molar mass. Molar mass is the
