konsentrasjonsuttrykk
A konsentrasjonsuttrykk, or concentration expression, is a mathematical formula used to describe the composition of a solution. It quantifies the amount of a solute present in a given amount of a solvent or a solution. Several types of concentration expressions exist, each suited for different applications and levels of precision.
Commonly used expressions include molarity, which is defined as the number of moles of solute per liter
The choice of concentration expression depends on the context. For chemical reactions, molarity is often preferred
