Question

1. report the measurement below, in milliliters, to the correct number of significant figures.

o 5.50 ml
o 5.69 ml
o 5.6 ml
o 56.2 ml

Explanation:

Step1: Observe the graduated - cylinder

The graduated - cylinder has markings. The major markings are for 5 mL and 6 mL, and there are smaller divisions. Each small division represents 0.1 mL.

Step2: Determine the meniscus position

The meniscus (the curved surface of the liquid) is between 5.6 mL and 5.7 mL. We estimate the last digit. It appears to be closer to 5.6 mL.

Answer:

5.6 mL
