Which lab equipment tool would you use to measure approximately 50 ml of salt water? explain

Graduated cylinder because it is extremely precise

Explanation:

In a chemistry lab, volume of chemicals can be measured by several tools such as beakers, flasks, burets, pipets , graduated cylinder etc. Out of these, I would preferably use graduated cylinder for measuring 50 ml of salt water. It is so because graduated cylinder have a high accuracy of 1% which means a cylinder of 10 mL can measure a volume of 0.1 mL accurately. Usually the common sizes in which graduated cylinders are available ranges from 5 mL to 3000 mL
