Answer 1

Answer #1

The uncertainty of pipette in delivering 100mL ofvsolution= +/- 0.05mL.

Now pipette is used 3 times to deliver 300mL of solution.

Since we are adding the volume 3 times, the uncertainty will also be added.

Total uncertainty=0.05mL+0.05mL+0.05mL Uncertainty in 300mL = 0.15mL

300mL +/- 0.15mL
