A 4.4-mL sample of a 0.14 M HCl(aq) solution was mixed with a 6.3-mL sample of a 0.68 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 16 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.

HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(1) 100.0 mL of 0.500 M HCl is mixed with 300.0 mL of 0.100 M NaOH in a coffee cup calorimeter. Assuming the temperature of the solution was initially 25.0 °C, and the final temperature of the solution was 26.7 °C, calculate the enthalpy of this reaction per mole of HCl. Assume the density of the water and acid and base solutions are all 1.00 g/mL.
