Q3.1 3 Points A 12.0 M stock solution of HCl(aq) is diluted with water to give...
50.0 mL of a stock solution of hydrochloric acid, HCl (aq), at 12.0 M is diluted by adding it to 150.0 mL of water, H2O. What is the concentration, in units of molarity, of the final, diluted solution?
Question 8 (2 points) A 6.5-ml sample of a 0.11 M HCl(aq) solution was mixed with a 4.1-mL sample of a 0.70 M HCl(aq) solution. Calculate the pH of the mixture. Provide your answer to the correct number of decimal places. Your Answer: Answer Hide hint for Question 8 There is no reaction. You are simply mixing two solutions of the same acid. First calculate the molarity of the mixture and finally the pH of the mixture.
