Tömegwázalék

Tömegwázalék, often translated as mass percentage or weight percentage, is a common way to express the concentration of a component in a mixture or solution. It quantifies the mass of a solute or component relative to the total mass of the solution or mixture, multiplied by 100. The formula for calculating mass percentage is: (mass of component / total mass of mixture) * 100%. For example, if you dissolve 10 grams of salt in 90 grams of water, the total mass of the solution is 100 grams. The mass percentage of salt would be (10 g / 100 g) * 100% = 10%. Similarly, the mass percentage of water would be (90 g / 100 g) * 100% = 90%. This unit of concentration is widely used in chemistry, pharmacy, and manufacturing because it is independent of temperature and pressure changes, unlike volume-based concentration units. It is particularly useful when dealing with solid-in-liquid solutions, but can also be applied to mixtures of solids or liquids. Understanding tömegwázalék is fundamental for stoichiometry calculations and for accurately preparing solutions of desired concentrations.
