Question

1. report the measurement below, in milliliters, to the correct number of significant figures. 6.6 ml 6.250 ml 6.33 ml 6.3 ml

Explanation:

Step1: Identify scale division

The graduated - cylinder has markings. Each small division between 6 and 7 represents 0.1 mL.

Step2: Read the meniscus

The bottom of the meniscus (the curved surface of the liquid) is between 6.2 and 6.3. Estimating the value, it is closer to 6.3. When reading a graduated - cylinder, we estimate one digit beyond the smallest marked division. So the measurement is 6.3 mL considering significant figures rules for measurement.

Answer:

6.3 mL
