tömegszázaléka

Tömegszázaléka is a Hungarian term that translates to "mass percentage" in English. It is a unit of concentration used in chemistry to express the proportion of a solute within a solution. Specifically, it represents the mass of the solute divided by the total mass of the solution, multiplied by 100.

The formula for calculating mass percentage is:

Mass Percentage = (Mass of Solute / Mass of Solution) * 100

The mass of the solution is the sum of the mass of the solute and the mass of the solvent. For example, if you dissolve 10 grams of salt (solute) in 90 grams of water (solvent), the total mass of the solution is 100 grams. The mass percentage of salt in this solution would be (10 g / 100 g) * 100 = 10%.

Mass percentage is often used when preparing solutions in laboratories or in industrial settings. It is a dimensionless quantity, as the units of mass cancel out in the calculation. It is a common way to express the strength or concentration of a mixture, particularly when dealing with solid solutes dissolved in liquid solvents. This method of expressing concentration is straightforward and does not require knowledge of molar masses or volumes, making it practical for many applications.
