An anctacid tablet was dissolved in 26.00ml of 0.650M HCl. Theexcess acid was back titrated with eactly 11.34ml of 1.05M NaOH.The average weight of a tablet is 0.834g. The tablet came from abottle 150 tablets that cost $3.99.
a. Calculate the moles of HCl neutralized by the tablet. (molesof HCl(aq) neutralized per tablet = moles of HCl(aq) added to theantacid - moles of NaOH required to backtitrate)
b. Calculate the mass effectiveness of the antacid. (masseffectiveness = moles of HCl(aq) neutralized per tablet / mass ofantacid (g))
c. Calculate the cost effectiveness of the antacid. (costeffectiveness = moles of HCl(aq) neutralized per tablet / price oftablet (cent))
