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.

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
