Question

the calibration is to 1 ml, so we estimate another digit. what is the volume of liquid in the cylinder? 67 ml 67.4 ml 68 ml 68.0 ml

Explanation:

Step1: Determine the meniscus position

The meniscus is the curved surface of the liquid. In this graduated cylinder, we note the major and minor markings. The major markings are \(10\) mL apart (\(60\), \(65\), \(70\) mL). The minor markings (between \(65\) and \(70\)) are \(1\) mL apart.

Step2: Estimate the value

The meniscus is above \(67\) mL. Since the calibration is \(1\) mL, we estimate to the tenths place. The meniscus is approximately \(0.4\) mL above \(67\) mL.

Answer:

\(67.4\) mL
