The formula for the concentration of a solution is:

M = Mass of solute/ Molar mass *Volume of solution

Where M is concentration in Molarity, Mass is in grams, and the volume of solution is in liters.

To prepare 0.1 M sodium acetate, you will need to use the following formula:

Mass of sodium acetate = M * Volume of solution

Mass of sodium acetate = Molar mass of sodium acetate(NaCH3COO)

The molar mass of sodium acetate is 82.03 g/mol. So, to prepare 1 L of 0.1 M sodium acetate, you will need:

Mass of sodium acetate = 0.1 M * 1 L * 82.03 g/mol = 8.203 g

Step 2: Dissolve the sodium acetate in a small volume of water

In a beaker or flask, add about 50-100 mL of distilled water. Add the calculated amount of sodium acetate and stir until it is completely dissolved.

Step 3: Transfer the solution to a volumetric flask

Use a graduated cylinder or pipette to transfer the sodium acetate solution to a 1 L volumetric flask.

Step 4: Add more water to reach the mark

Add distilled water to the volumetric flask until the solution reaches the 1 L mark. Swirl the flask gently to mix the solution.

Step 5: Mix well

Stir or swirl the solution thoroughly to ensure that the sodium acetate is evenly distributed throughout the solution.

Step 6: Store properly

Store the prepared sodium acetate solution in a clean and labeled container. Keep the container tightly closed to prevent evaporation. Sodium acetate solutions should be kept at room temperature.
