Prepare 50 mL of an aqueous solution of 0.10M NaHCO3 (sodium bicarbonate, baking soda). 1. Determine how many grams of sodium bicarbonate are required. Show all steps for this calculation, using dimensional analysis with units clearly identified. 2. Prepare this aqueous solution, using a volumetric flask for the precise final volume measurement. It is not a problem to use tap water. 3. Clearly write the procedure (step by step) for making this solution.
