How many atoms are in 5.5 mol 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.
What elements mass is 30 and a noble gas but not neon?
There is no such noble gas with an atomic mass of 30. The mass of neon is 20 and the mass of the next noble gas, argon, is 40
Which gas has the lowest mass per mole?
Hydrogen
What is the volume of 0.05 mol of neon gas at stp?
56.5/4= 14.125mols 14.125 X 22.5dm3 = 317.8125dm3
If you had 40.0 grams of neon light how many mole you have?
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.

What is macroscopic sample of neon?
The chemical symbol (not formula, macroscopic sample) of neon is Ne.
What elements mass is 30 and a noble gas but not neon?
There is no such noble gas with an atomic mass of 30. The mass of neon is 20 and the mass of the next noble gas, argon, is 40
The molar mass of a gas can be determined from?
for Apex: can be found easily from the periodic table is the mass of a mole of the gas
A 1.0-mole sample of krypton gas has a mass of?
Since one mole is 6.02e23 of any atom, the atomic weight is equal to one mole of any element. For example, one mole of Ca is 40.08, one mole of S is 32.07. Thus being said, one mole of krypton is 83.80!
What is the atomic mass 20 and is a gas?
Neon
What has atomic mass 20 and is a gas?
Neon.
Which gas has the lowest mass per mole?
Hydrogen
When nitrogen gas is added to a sample of neon gas in a closed container the pressure inside the container?
increases
What is the mass of 1 mole of gas?
39.95 because that is the molar mass of Argon
If a sample of neon gas occupies a volume of 2.8L at 180Pa what will its volume be at 120Pa?
N/A if you had neon gas to begin with, you would be radioactive. I would know these things you see.
What is the mass of 1 Mole of diatomic nitrogen gas?
28g
