Answer:
The uncertainty due to the equipment on chemistry equipment is equal to +-1/2 of the smallest unit marked in your equipment; in this case you have a pipette and its sameelst mark is 0.1 mL, so the uncertainty will be 0.05 mL. If you divide 0.05 mL / 3.2 mL and multiply it by 100 you get 1.56% of uncertainty if you measure 3.2 mL, so it will be proper to report the measurement and also the uncertainty.
0.074Hz is the answer to that
