Conc. of HCl = 0.0979 M
Conc. of NaOH = 0.1006
#1 Mass of sample - 0.116 g
Vol. of HCl added = 28.0 ml
moles of HCl added initially : (28.0 ml / 1000 ml/L)* 0.0979 mol / L =0.00274 mol
vol. of NaOH added for titration = 15.2 ml
Moles of NaOH used = (15.2 ml / 1000 ml/L)* 0.1006 mol / L =0.001529 mol
Since, 1 mol of NaOH = 1 mol of HCl
So, mol of HCl reacted with NaOH = 0.001529 mol
Moles of HCl neutralized by Antacid : 0.00274 mol-0.001529 mol = 0.0012 moles
Mass of tablet : 0.116 g
Moles of HCl neutralized by per g of Antacid tab. = 0.0104 moles
#2 Mass of sample - 0.104 g
Vol. of HCl added = 22.0 ml
moles of HCl added initially : (22.0 ml / 1000 ml/L)* 0.0979 mol / L =0.002154 mol
vol. of NaOH added for titration = 18 ml
Moles of NaOH used = (18 ml / 1000 ml/L)* 0.1006 mol / L =0.001811 mol
Since, 1 mol of NaOH = 1 mol of HCl
So, mol of HCl reacted with NaOH = 0.001811 mol
Moles of HCl neutralized by Antacid : 0.002154 mol-0.001811 mol = 0.000343 moles
Mass of tablet : 0.104 g
Moles of HCl neutralized by per g of Antacid tab. = 0.0033 moles
Average Moles of HCl neutralized by per g of Antacid tab. = 0.0069 moles
Average Moles of HCl neutralized by per Antacid tab. = 0.0089 moles
Cost of antacid per tablet : 4.5 $
Cost antacid per tablet per Moles of HCl neutralized = 1.00 * (4.5 $/per 0.0089 mol) = 505.6 $/mol
