6.226 x 10^28 atoms of Nitrogen approximately
mole = 6.226 X 10^28 objects
Nitrogen exists as a diatomic molecule, so in 0.5 moles of diatomic nitrogen gas there are exactly 1 moles worth of molecules, therefore the number of atoms in 0.5 moles of nitrogen gas is equal to the value of the mole which is approximately 6.226 x 10 ^ 28 atoms
0.5 moles sulfur (6.022 X 1023/1 mole S)
= 3 X 1023 atoms of sulfur
===================
There are 3.011x10^23 atoms in 0.5 mol Ar.
0.5 mol x 6.022x10^23 atoms/mol = 3.011x10^23 atoms
It is 0.5*Avogadro's constant = 3.011*10^23 atoms, approx.
The number of atoms is 3,011.10EX23.
The number of atoms is 3,011 o70.10e23 (for atomic chlorine, Cl).
The answer is 6,022.10e23 atoms.
mostly nitrogen, two nitrogen atoms bound into a nitrogen molecule (N2) then oxygen, two oxygen atoms bound into an oxygen molecule (O2) then argon - one argon atom (it almost never binds to other atoms) Ar the traces of many, many other gases.

For this you need the atomic (molecular) mass of NaHCO3. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaHCO3=84.0 grams110 grams NaHCO3 / (84.0 grams) = 1.31 moles NaHCO3
No. If it is written Ar, it is the element Argon. If not, it may be the acronym for a longer-named compound, but it cannot be a chemical formula.
An Angstrom (symbol: Å) is a unit of measure.The Angstrom unit is most suitable for describing a measurement of atomic distance, the the distance between two atoms in a molecule.For example the main gaseous components of air are: 78% Nitrogen (N2), 21%Oxygen (O2) and 1% Argon (Ar).The Angstrom unit is used to measure some of the size attributes of these gases:N2 gas has 2 atoms of Nitrogen, O2 gas has 2 atoms of Oxygen. Argon gas is a single atom.N2 gas has 2 atoms attached with a bond length of 1.09 ÅO2 gas has 2 atoms attached with a bond length of 1.21 ÅN2 gas has a diameter of 3.16 Å *O2 gas has a diameter of 2.96 Å *Ar gas has 1 atom with mean radius of 0.95Å* This is a "gas viscosity kinetic diameter" as N2 and O2 are not spherical.The Angstrom unit is one ten-billionth of a meter.To put the Angstrom size in perspective:1.0 Meter, 1 M0.01 ^10-2 CentiMeter, hundredth, 1/100 M0.001 ^10-3 MilliMeter, thousandth, 1/1,000 M0.000001 ^10-6 MicroMeter, millionth, 1/1,000,000 M (aka. micron)0.000000001 ^10-9 NanoMeter, billionth, 1/1,000,000,000 M0.0000000001 ^10-10 Angstrom 10 billionth, 1/10,000,000,000 M0.000000000001 ^10-12 PicoMeter, trillionth, 1/1,000,000,000,000 MDuncanMiles - Science Writer (original contributor)

No, hydrogen is a diatomic atom, which means it bonds with itself naturally, and since argon it is a noble gas, it is found alone in nature. This means that 1 molecule of hydrogen has two atoms, while 1 molecule of Argon has 1 atom.
The number of atoms is approx. 19,98.10ex.23
2.3 × 1024 atoms of Ar
From the Periodic Table, Argon has an atomic weight of 39.948. One mole of any element is equal to its atomic weight in grams. So 1 mole of Ar = 39.948g of Ar. Using that equality, you do the following calculation to find the number of moles of Ar in 22g of Ar: 22g Ar X 1mol Ar/39.948g Ar = 0.55mol Ar
First from atoms to mole (Avogadro's number)2.3*10+24 (atoms) / 6.022*10+23 (atoms/mole) = 3.82 mole Agand from mole to gram (via molar mass)3.82 mole * 107.9 g/mole = 412 g Ag
Mole = Mass/RMM Ar for Na=23 & Ar for Cl = 35.5 Therefore 1mole = Mass / (35.5+23) 1 mole of NaCl is 58.5g Mole = Mass/RMM Ar for Na=23 & Ar for Cl = 35.5 Therefore 1mole = Mass / (35.5+23) 1 mole of NaCl is 58.5g But that can be misleading. NaCl does not form into molecules (and salts in general do not). If you dissolve 58.5g of NaCl into water, it will dissociate into ions, and there will be 2 moles of particles in solution: 1 mole of Na+ ions, and 1 mole of Cl- ions. Knowing that will be important for calculating various things, such as how many degrees the freezing point will be depressed, when you dissolve so much salt in so much water.
(6.02*10^24)*0.44 = 2.6488*10^24In 1 mol of any element there are 6.02*10^24 atoms.
Ar of S = 32.1g/mol Number of moles = 1.2g / 32.1g/mol = 0.0374mol One mole of a substance has the same number of particles as the Avogadro constant, which 6.02 x 10^23 Therefore, number of atoms = 0.0374 x 6.02 x 10^23 = 2.250 x 10^22 atoms
