Question 5 (10 points) If a student determined that 0.02351 moles of HCl was initial added to the beaker and 0.008952 moles of NaOH was calculated for the back titration. How many moles of HCl were neutralized by the antacid tablet (Note: the molar ratio of the reaction is 1:1 ; so there are 1 mole of HCI-to-1 mole of...
