Question
B: Alkali Content of Antacid Used ef antack of of HCI volume, ml Moles of HCI used, mol Grams of HCI used, g Grams of HCI per 1 gram antacid 7. Calculate the volume of HCI added to the antacid solution, Place the results in the data table, above 8. Calculate the moles of HCI added to the solution. Use the volume of HCI and the molarity of HCI for this calculation. Show all work below. Place results in the data table, above. 9. Calculate the mass(ß) of HCl added to the solution. Use the moles of HCI and the molar mass of HCI (36.5 g - 1 mol) for this calculation. Show all work below. Place the results in the data table, above.Explanation / Answer
8) For Run 1,
[ molarity of HCl used is not mentioned in the data table however this is procedure to calculate]
Volume of HCl used = 2.2 mL = 2.2*10-3 L
moles of HCl added to the solution = Molarity of HCl used * 2.2*10-3L
Similarly for Run 2,
Volume of HCl used = 2.8*10-3 L
moles of HCl added added to the solution = Molarity of HCl used * 2.8*10-3L
[ mol = molarity units in mol/L * volume in L]
9) For Run 1 and Run 2
mass of HCl added to the solution = moles of HCl added to the solution * 36.5 gm/mol
[ gm = mol * gm/mol ]
