10 grams
It's actually 20 grams. Reason is that the ATM on the periodic table is 20ATM, so therefore the mass is 20 grams. The person who wrote 10 grams is a troll.
1 mole of neon is 20.1797 g
So, 0.056 mole will weigh 1.130 g
neon weighs 20.1797 amu's
Neon's got an atomic number of 20, so if you had 40 grams of neon gas you'd have around two moles of it. But neon LIGHT? Light's weightless, dude.
Two moles of neon contain 12,044281714.10e23 atoms.
0,125 L neon is equivalent to 0,0056 moles.
1 mole = 20.18 g of Neon = 6.023 x 1023 atoms of neon (A neon molecule has only one atom) So, 39 moles = 39 x 6.023 x 1023 atoms = 234.897 x 1023 atoms of neon
Neon is a monatomic gas (1 atom/entity), so finding the number of atoms is as simple as multiplying the quantity of gas by the number of entities in a mole: (5.00 moles Ne gas) (6.022 X 1023 entities/1 mole Ne gas) (1 atom of Ne/entity) = 3.01 X 1024 atoms of Ne ------------------------------------------ You may notice that if the units are treated as factors, they cancel, leaving the desired unit (atoms) at the end.

The first step is to identify what you have and what you need. The units of our data is grams. The units that we desire is number of atoms. Therefor, to answer this question, we need two important tools of chemistry: the periodic table, where we can find the molar mass of the element (bottom of the element's box), and Avogadro's number, which is the number of atoms in one mole.Going to our periodic table, we find the molar mass to beM=20.1797 grams/moleand Avogadro's number isNA=6.022*1023 atoms/moleTo make the conversion, we simply track our units through the calculation:80 grams of Ne * 1 mole Ne/20.1797 grams Ne * 6.022*1023 atoms Ne/mole Ne=2.39*1024 atoms NeIt is worth noting that any conversion factor can be reversed by reciprocating the value. In the above example, the molecular mass is given in grams per mole, which can be used to convert moles to grams. The reciprocal was used to convert grams into moles.
0.251 moles neon (6.022 X 1023/1 mole Ne) = 1.51 X 1023 atoms of neon -------------------------------------

The answer is 69.7247149193
The mass of 1 atom of neon is 20 amu. It doesn't form molecules
4444.00
Neon molecule is mono-atomic. 20.18 g (1 mole) of neon will have 6.023 x 1023 atoms of neon
