(Analysis) A student was measuring out chemicals in the lab and used a graduated cylinder with graduation down to 0.5 mL and a flask with a graduation down to 1 mL. He measured 12.5 mL in the graduated cylinder and 2.5 mL in flask. Were his measurements correct?
What is no, the graduated cylinder has graduation down to 0.5 mL which means he would have to estimate another digit. For example, 12.52 is much different than 12.59.
