A chemist dispenses a titrant 0.1000M HCl from a burette at 25 degrees celsius. the initial reading is taken six times; the values (in millimeters) are 6.79, 6.78, 6.79, 6.77, 6.76, 6.78. The final reading is also taken six times times; the values are 28.02, 28.03, 28.01, 28.02, 28.02, 28.03.
Calculate the number (n) of moles of HCl in the solution dispensed. Give S and Sm for the initial and final volumes, and give a limit of error (95 percent confidence) for n.
