The density of an object with a volume of 5.0ml and a mass of 20.0g is
15.0g/ml
0.25g/ml
100.0g/ml
4.0g/ml

The density of the object will be 4 g/ml.

Explanation:

Density is defined as the mass contained per unit volume.

Given : Mass of object = 20.0 grams

Volume of object=

Putting in the values we get:

Thus density of the object will be 4 g/ml.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
