Question

what volume is indicated on each of the graduated cylinders below? the unit of volume is ml.

Explanation:

Step1: Identify scale intervals

For each graduated - cylinder, first determine the value of each scale interval.

Step2: Read the meniscus

The volume is read at the bottom of the meniscus (the curved surface of the liquid).

a)

The scale interval is 1 mL. Reading the bottom of the meniscus, the volume is 55 mL.

b)

The scale interval is 0.1 mL. Reading the bottom of the meniscus, the volume is 4.2 mL.

c)

The scale interval is 1 mL. Reading the bottom of the meniscus, the volume is 25 mL.

d)

The scale interval is 1 mL. Reading the bottom of the meniscus, the volume is 17 mL.

e)

The scale interval is 75 - 70=5 mL. Reading the bottom of the meniscus, the volume is 77 mL.

f)

The scale interval is 0.2 mL. Reading the bottom of the meniscus, the volume is 4.6 mL.

g)

The scale interval is 5 mL. Reading the bottom of the meniscus, the volume is 35 mL.

h)

The scale interval is 0.2 mL. Reading the bottom of the meniscus, the volume is 3.6 mL.

i)

The scale interval is 2 mL. Reading the bottom of the meniscus, the volume is 46 mL.

Answer:

b) 4.2 mL
c) 25 mL
d) 17 mL
e) 77 mL
f) 4.6 mL
g) 35 mL
h) 3.6 mL
i) 46 mL
