Concentration is the measure of the amount of a solute that is dissolved in a given quantity of solvent. It is commonly expressed in terms of molarity (M), which is moles of solute per liter of solution.
5 Must Know Facts For Your Next Test
The formula for molarity (M) is $\frac{moles\,of\,solute}{liters\,of\,solution}$.
A solution with a high concentration has more solute particles per unit volume than a solution with low concentration.
Dilution involves reducing the concentration of a solution by adding more solvent.
The units for molarity are typically moles per liter (mol/L).
When preparing solutions, it’s crucial to precisely measure both solute and solvent to achieve the desired concentration.
