Answer:

Wind farms, nuclear power plant, and hydroelectric power plants

Explanation:

Winds farms:

Pros: Creates electrical energy easily, doesn't cause pollution and no fossil fuels.

Cons: Only works in windy climates, hard to function.

Nuclear plants:

Pros:Creates electrical energy out of wastes, very easy and doesn't require fossil fuels.

Cons: Causes mass pollution, very harmful to the ecosystem and humans.

Hydroelectric plants:

Pros: uses only water and turbines, no fossil fuels either.

Cons: Water usage causes faster evaporation, most dams overuse them.

Licemer1 [7]

Answer:

<h2>1.23 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{6.76 \times  {10}^{23} }{6.02 \times  {10}^{23} }  =  \frac{6.76}{6.02}  \\  = 1.22923...

We have the final answer as

<h3>1.23 moles</h3>

Hope this helps you
