This is kind of a pretty easy question:
- In order to get the number of atoms/entities of Neon, you will have to turn that 1009g of Neon into moles
-And then you have to use the moles and calculate it using Avogadro's Number which is 6.02 x 10^23
number of moles = mass/molar mass of element/compound
n = 1009g/20.18g/mol
n = 50 mol
Number of atoms/entities = 50 x (6.02 x 10^23)
Number of atoms in 1009g of neon is 3.01 x 10^25 (scientific notation because its a really long number)
The number of atoms = 4.8 x 10²² atoms
<h3>Further explanation</h3>
Given
5.9 g of Lithium carbonate
Required
The number of atoms
Solution
mol Lithium carbonate(MW=73.9 g/mol) :
= mass : MW
= 5.9 g : 73.9 g/mol
= 0.08
The mole is the number of particles(molecules, atoms, ions) contained in a substance
<em>1 mol = 6.02.10²³ particles
</em>
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
So for 0.08 mol :
= 0.08 x 6.02.10²³
= 4.8 x 10²² atoms

Explanation:
Methyl butanoate is an ester. Esters have the general molecular formula, RCOOR where the two Rs may represent the same or different alkyl groups.
Methyl butanoate is has a fruity odor, smelling like apples or pineapples fragrance. It is also called methyl butyrate.
