Sure, here are the steps to prepare 100ml of 0.05M Na2CO3 solution:

1. First, calculate the amount of Na2CO3 needed. The molar mass of Na2CO3 is approximately 105.99 g/mol. So, for a 0.05M solution in 100ml, you would need:

(0.05 moles/liter) * (105.99 g/mole) * (0.1 liters) = 0.52995 g

So, you would need approximately 0.53g of Na2CO3.

2. Weigh 0.53g of Na2CO3 using an analytical balance.

3. Dissolve the weighed Na2CO3 in a small amount of distilled water (less than 100ml) in a beaker. Stir the solution until the Na2CO3 is completely dissolved.

4. Transfer the solution into a 100ml volumetric flask.

5. Add more distilled water into the flask until the bottom of the meniscus is at the 100ml mark.

6. Cap the flask and invert it several times to ensure the Na2CO3 is evenly distributed throughout the solution.

Now you have 100ml of 0.05M Na2CO3 solution.
