Question

the calibration is to 1 ml so we can estimate another digit. what is the volume in the cylinder?

Explanation:

Step1: Observe the meniscus

The meniscus is between 53 and 54 on the graduated - cylinder.

Step2: Make an estimate

Since the calibration is 1 mL and we can estimate an extra digit, and the meniscus is closer to 54 than 53, and a bit below the middle between 53 and 54. An estimate of 53.9 mL is reasonable.

Answer:

53.9 mL
