A chemist dispenses a titrant, 0.1000 M HCl, from a buret at 25degreeC. The initial reading is taken six times with values (in milliliters) of 6.79, 6.78, 6.79, 6.77, 6.76, and 6.78. The final reading is also taken six times; the values are 28.02, 28.03, 28.01, 28.02, 28.02, and 28.03. (Note: this is not 6 pairs of initial and ?nal readings rather 6 initial buret readings and 6 ?nal readings.) Calculate the number of moles of HCl in the solution dispensed and its associated error.
