In your first task, you are required to prepare a 100 mL solution of sodium bicarbonate at a concentration of 0.50 M. Complete the following table and calculate the mass of sodium bicarbonate needed to prepare this solution. Molecular weight of sodium bicarbonate Required final concentration Required final volume Amount of sodium bicarbonate needed to make 1 L at 0.5 M Amount of sodium bicarbonate needed to make 100 mL at 0.5 M Mass (g) = Amount (mol) × Molecular Weight (g/mol) Value 84.01 Now that you know the amount of sodium bicarbonate in mol needed to make your solution, you can convert this value into the mass by using the molecular weight of the compound. The following equation may be helpful: Mass of sodium bicarbonate needed to make 100 mL at 0.5 M Units g/mol M (mol/L) L mol mol g In the 100 mL 0.5 M solution, how many molecules of sodium bicarbonate have been added. Hint - In 1 mole there are 6.022 × 10²³ molecules.

III O Chemical Reactions Solving for a reactant in solution 1/5 Bis Sodium hydrogen carbonate (NaHCO3), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCI), which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO3 neutralizes excess HCI through this reaction: HCl(aq) + NaHCO3(aq) NaCl(aq) + H2O(l) + CO₂(9) The CO2 gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of a woman suffering from indigestion can be considered to be 150. mL of a 0.024 M HCl solution. What mass of NaHCO3 would she need to ingest to neutralize this much HCI? Round your answer to 2 significant digits. Ов X G
