Answer:
<h2>1.8662 × 10²⁴ atoms</h2>
Explanation:
The number of atoms can be found by using the formula
N = 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
We have
N = 3.1 × 6.02 × 10²³
We have the final answer as
<h3>1.8662 × 10²⁴ atoms</h3>
Hope this helps you
Answer:
The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.

Answer:
through Decantation
Explanation:
Decantation: Decantation is pouring out of upper clear layer of liquid into another container to separate two immiscible liquids or to separate different substances in a suspension mixture.
Therefore, we could use decantation once the sand particles settle down by gently pouring the water into another container. Once the water is transfered, we'll be left with sand in the bottom of the first container.
