In an experiment, 0.500 grams of sodium bicarbonate were added to an evaporating dish and an excess of 6.0 M hydrochloric acid was added. The bicarbonate bubbled with the addition of the aqueous HCl. The evaporating dish was gently swirled until the bubbling stopped. The evaporating dish was placed on a hot plate and heated carefully to dryness so that it was completely dry and at constant mass. The amount of sodium chloride obtained from the evaporating dish was 0.114 g. The reaction is given below. NaHCO3 (s) + HCl (aq) ---> NaCl (s) + CO2 (g) + H2O (l) Question: Is the reaction balanced?

(Assume that your drug dissolves in water, at least to the extent necessary for this problem.) Use complete sentences in your description of the solution preparation process. A patient is given 2.0mL of a 3.00% (m/v) solution of your drug, how many milligrams of the drug did they receive? What is the molarity of a 3.00% (m/v) solution of your drug?
A pipet is used to transfer 3.00 mL of a 2.00 M stock solution in flask “S” to a 25.00-mL volumetric flask “A,” which is then diluted with DI H2O to the calibration mark. The solution is thoroughly mixed. Next, 3.00 mL of the solution in volumetric flask “A” is transferred by pipet to a 50.00-mL volumetric flask “B” and then diluted with DI H2O to the calibration mark. Calculate the molarity of the solution in volumetric flask “B.”
