It is necessary to dispense 30 mL as accurately as possible. The choices are one 5 mL pipette six times, six different 5 mL pipettes, a 25 mL graduated cylinder, a 50 mL burette, or a 100 mL beaker. Assume the only error introduced was by the variance in the glassware, determine the cumulative error for each instrument. The Pipette -5ml = +/- 0.01 ml , Burette - 50 ml= +/- 0.05 ml, Graduated cylinder - 25 ml = +/- 5%, Beaker -100 ml = +/- 10%.
