To calculate the Final Molarity (M2):
\[ M2 = \frac{M1 \times V1}{V2} \]
Where:
Molarity dilution is the process of decreasing the number of moles of a substance per volume of a solution through the process of dilution.
What is dilution? Dilution is the decreasing of a concentration of a substance through adding a base or another substance.
Let's assume the following values:
Step 1: Use the molarity dilution formula:
\[ M2 = \frac{M1 \times V1}{V2} = \frac{2 \times 1}{4} = 0.5 \text{ moles/L} \]
The Final Molarity is 0.5 moles/L.
