Which tool has the greatest degree of precision? a beaker with markings every 50 ml a flask with markings every 25 ml a graduated cylinder with markings every 1 ml a pipette with markings every 0.1 ml

I think the correct answer would be the last option. The tool that has the greatest degree of precision would be the pipette with markings every 0.1 mL. Precision is the closeness of data to each other. For instruments, we call one instrument as more precise, if this instrument would allow us to measure substances specifically. The beaker would be less precise since we can only measure liquids only at 50 mL intervals. Also, the flask would be less precise since we can only measure with a 25 mL intervals only however this would be more precise than the beaker. Lastly, the pipetter would have the most precision since we can measure up to the first decimal place.
