240 4. A Rolaids tablet contains calcium carbonate for neutralizing stomach acid. If a Rolaids tablet neutralizes 24.65 mL of 0.547 M hydrochloric acid, how many milligrams of calcium carbonate are in a Rolaids tablet? CaCO3 (s) + 2 HCl(aq) → CaCl2 (aq) + H₂O(1) + CO₂(g) 5. (optional) A student diluted 15.0 mL of 6 M NaOH solution into 485.0 mL of distilled water. Calculate the molarity of the diluted base solution. Explain why this diluted NaOH solution cannot be used as a standard solution.
