Volume measurements will be made using a 25-ml graduated cylinder, which has major scale divisions marked every 2 ml and minor scale divisions every 0.2 ml. what is the estimated uncertainty in the volume measurements

The estimated uncertainty is ±0.1 ml

Explanation:

Measurements are usually associated with uncertainty which depends on the instrument used or the procedure employed.

It is given that the graduated cylinder of volume 25 ml has a major scale marked every 2 ml and minor scale with 0.2 ml. In general measurements made with graduated cylinders can be estimated one decimal place beyond the smallest division. In this case, the volume of the liquid can be read to the nearest 0.1 division. Hence, the uncertainty would be ± 0.1 ml.
