Térfogatszázalékban

Térfogatszázalékban, often abbreviated as "térf%" or "vol%", is a unit of concentration used in chemistry and other scientific fields. It expresses the volume of a solute as a percentage of the total volume of the solution. The formula for calculating térfogatszázalékban is: (Volume of solute / Volume of solution) * 100%. Both the solute volume and the solution volume must be measured in the same units, typically milliliters (mL) or liters (L).

This method of expressing concentration is particularly useful when dealing with liquid-liquid solutions or when the volume of the solute is significant. For example, if you mix 10 mL of ethanol with 90 mL of water, the total volume of the solution is approximately 100 mL (though some volume contraction may occur in reality). In this case, the concentration of ethanol would be (10 mL / 100 mL) * 100% = 10% térfogatszázalékban. It is important to note that térfogatszázalékban is an approximation and can be affected by intermolecular interactions that cause volume changes upon mixing. For precise calculations, mass-based concentrations like mass percent or molarity are often preferred.
