  3. It's the precision of the pipette. It means if you measure to the line, the volume will be +/- 1/100th of an ml.

  7. One way to do it: 1/100 is the ratio of the concentrations right? Therefore you want (53 x 100) or 5300 mL total volume. 5300 - 53 = 5247mL water added.

  9. 2ul, 0.2ul and 0.02ul of the initial solution made up to 20ul with diluent in each case. In practice, you would not attempt to measure these small volumes in a laboratory but would make serial dilutions, (using the same pipettes,with fresh tips, in each case).
