Molekulaszázalék

Molekulaszázalék, often translated as mole percent, is a unit of concentration that expresses the proportion of a particular component in a mixture as a percentage of the total number of moles of all components. It is calculated by dividing the number of moles of the component of interest by the total number of moles in the mixture, and then multiplying the result by 100. For example, if a mixture contains 2 moles of substance A and 3 moles of substance B, the mole percent of substance A would be (2 moles / (2 moles + 3 moles)) * 100 = 40 mole percent. Mole percent is a dimensionless quantity and is commonly used in chemistry and materials science, particularly when discussing solutions, alloys, and gas mixtures. It is independent of temperature and pressure, making it a useful measure for comparing compositions under varying conditions. Unlike mass percent or volume percent, mole percent directly relates to the number of individual particles present in a mixture, which can be significant when considering chemical reactions or physical properties that depend on the number of molecules.
