Noble Gases is the answer. These elements have a full outer shell composed of eight valence electrons, meaning that they do not need to gain electrons from other elements in reactions, making them nonreactive (inert).

Gold is often used with other metals, such as copper and zinc, to make jewelry. Approximately 58% of the mass of a certain 40 gr
Oduvanchick [21]

Answer:

1.2 cm³.

Explanation:

The following data were obtained from the question:

Mass of neckl = 40 g

Density of gold = 19.3 g/cm³

Volume of gold =..?

Next, we shall determine the mass of the gold in the necklace.

From the question given above, we were told that 58% of the mass of the necklace is gold. Thus, we can obtain the mass of the gold in the necklace as follow:

Mass of neckl = 40 g

Mass of gold =?

Mass of gold = 58% × 40

Mass of gold = 58/100 × 40

Mass of gold = 23.2 g

Therefore, the mass of the gold in the necklace is 23.2 g

Finally, we shall determine the volume of the gold in the necklace as follow:

Density of gold = 19.3 g/cm³

Mass of gold = 23.2 g

Volume of gold =..?

Density = mass /volume

19.3 = 23.2/Volume

Cross multiply

19.3 × Volume = 23.2

Divide both side by 19.3

Volume = 23.2 / 19.3

Volume of gold = 1.2 cm³

Therefore, the volume of the gold in the necklace is 1.2 cm³
