In 58.2 grams of Na there is 1.51 x 10^24 atoms.
<h3>Mole calculation</h3>
To calculate the amount of atoms present in a mass sample, it is necessary to have knowledge of the molar mass of the element and Avogadro's constant, used in such a way that:
Now, with the value of the number of moles, just calculate the number of atoms present, so that:
So, in 58.2 grams of Na there is 1.51 x 10^24 atoms.

Answer:
a. size and composition
Explanation:
The inner planets differs from the outer planets mostly and mainly in terms of their sizes and composition.
Inner planets are also know as the terrestrial planets. They are the first four planets closest to the sun. They are mostly solids with rocky masses.
The outer planets are located beyond the asteroid belts. They are the last four planets before the Kuiper belt objects. These planets are also called Jovian planets predominantly made up of gases.
The inner planets are smaller compare to the outer planets in size.
The outer planets are gas giants and the inner planets are rocky masses.
Peter is taller, convert cm to in.
Answer:The oxygen during photosynthesis comes from split water molecules. During photosynthesis, the plant absorbs water and carbon dioxide. After the absorption, the water molecules are disassembled and converted into sugar and oxygen.
