The formula to calculate the number of moles (n), concentration (C), or volume (V) is:
\[ n = C \cdot V \]
Where:
Let's say the concentration (\( C \)) is 2 M, and the volume (\( V \)) is 3 L. Using the formula:
\[ n = 2 \cdot 3 \]
We get:
\[ n = 2 \cdot 3 = 6 \text{ moles} \]
So, the number of moles (\( n \)) is 6 moles.
Concentration, often referred to as molarity, is a measure of the amount of a substance (solute) present in a given volume of solution. It is typically expressed in moles per liter (M). Concentration is a crucial concept in chemistry as it helps in understanding the strength and reactivity of solutions. Higher concentration means more solute particles are present in the solution, which can affect the rate of chemical reactions and the properties of the solution.
