factor of 100 to obtain 2.250m/mL. Two possible methods of dilution are stated. For each method, calculate the resulting absolute uncertainty in concentration. Use the manufacturer's tolerances in the table for uncertainties. Method A: Dilute 10.00mL up to 100mL with a transfer pipet and volumetric flask. Then take 10.00mL of the dilute solution and dilute it again to 100mL. absolute uncertainty; incerrest Method B: Dilute 1.000mL up to 100mL with a transfer pipet and volumetric flask. absolute uncertainty: Why is one method more precise than the other? Method B is less precise because the pereent relative uncertainty in the 1 -mL pipet is 0.6%, which is 3 times larger than the uncertainties of the other glassware. Method B is less precise because the absolute uncertainty in the 1mL pipet is 0.006mL, which is smaller than the uncertainties of the other glassware. Method B is more precise because the percent relative uncertainty in the I-mL pipet is 0.6%, which is 3 times langer than the uncertainties of the other glassware. Method B is more precise because the absolute uncertainty in the 1-mL. pipet is 0.006mL, which is smaller than the uncertainties of the other glassware
