Question

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

o 83 ml
o 84 ml
o 84.8 ml
o 84.0 ml

Explanation:

Step1: Identify scale division

The graduated - cylinder has markings. The difference between 80 mL and 90 mL is divided into 10 equal parts. So each division represents 1 mL.

Step2: Read the meniscus

The bottom of the meniscus (the curved surface of the liquid) is between 84 mL and 85 mL. Estimating the fraction of the division, it is closer to 84 mL.

Answer:

84 mL
