The measurements were so small, the percent error in weighing would have surpassed any miscalculations due to not calibrating. b. A top-loading balance could be used, but an analytical balance would be preferred because it would be more accurate. 4. I would use the automatic pipetter (1mL-10mL) and a 20mL test tube to
