Two moles of neon contain 12,044281714.10e23 atoms.


There are 10 protons per atom of neon. In 20.02 moles of neon there are 1.206 E25 atoms. This is determined by using Avogadro's number. So, there are 1.206 E26 protons in 20.02 moles of neon.


O.8 moles of 122.4 L of neon at STP.


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 (Ne) is a noble gas and exists as a monatomic element.Atomic mass of Ne = 20.2Amount of He = 18.5/20.2 = 0.916molThere are 0.916 moles of neon in a 18.5g pure sample.


Neon is a gas at normal temperature and pressure.


Neon is an element, and at normal pressure and temperature, is a gas.


1 mole of neon is 20.1797 g So, 0.056 mole will weigh 1.130 g


Neon is a gaseous element. "1 neon" doesn't make much sense; you can have, for example, "1 liter of neon" or "1 kg of neon".


0.251 moles neon (6.022 X 1023/1 mole Ne) = 1.51 X 1023 atoms of neon -------------------------------------


6.022 x 1023 atoms of neon is 1 mole of neon atoms. One mole of any element's atoms is 6.022 x 1023 atoms.



Helium, neon, and hydrogen are all gases at standard temperature and pressure.


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.


Neon lights are usually with neon or other inert gases at a low pressure, where when voltage gets through they shine.


The number of electrons in an atom equal the atom's number on the periodic table. Neon is number 10, so neon has 10electrons.


Neon is a colorless inert gas at standard temperature and pressure.


1 mole of gas occupies 22.4 L at STP. So 56/22.4 = 2.5 moles. Neon has atomic mass of 20 and so 2.5 moles x 20 atomic weight = 50 so the mass is 50g.


high pressure, low temperature.


The number of protons is equal to atomic number: neon 10 has protons.


Use the ideal gas equation. PV = nRT (1 atmosphere)(X volume) = (0.350 moles Ne)(0.08206 L*atm/mol*K)(298.15 K) Volume = 8.56 Liters of neon gas ========================


a neon number is that where sum of cube of digits of a number is equal to the cube of number itself.
