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
The volume of 5.0 moles of 02 at STP is 100 litres.
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.

0.251 moles neon (6.022 X 1023/1 mole Ne) = 1.51 X 1023 atoms of neon -------------------------------------
The volume of a gas is the same as the volume of its container.

240 Assuming ideal gas behavior, doubling the pressure means reducing the volume by a factor of 2.
