A mole is that number of molecular units of a substance. The number is called the Avogadro constant, or Avogadro's number. (It is defined as the no. of atoms in 12 grams of carbon-12).
For example, Iron has the chemical formula Fe. So a mole of iron is (Avogadro's no.) Fe atoms.
Water has the formula H2O. A mole of water, then, is (Avogadro's no.) H2O molecules.

How a mole s formed?
A mole is formed if you don't wash you're face
Mole on your right breast that itches why is that?
Any mole that itches should be examined by a doctor.
Who is the mole inside the NSA in Splinter Cell?
Micheal Doughtry, but he is not really a mole, his computer had gotten hacked because it had low security
What is the definitions of a mole in science?
a mole is the number of atoms present in twelve grams of carbon 12, the most common isotope of carbon.
How do you convert particle to mole?
You need the initial mole that you want to turn into particle Use that multiply by the advogadro number (6.022x10*23 ) The particle is a big term for things like atoms, or anything for the name of something that add up to a mole. 2 mole of hydrogen X 6.022x10*23 particles / mole = the # of particles
How large is a mole in scientific notation?
6.022x10(to the 23rd power)
Is 1.11 mole more or less than 6.0221023 atoms?
One mole is approximately equal to Avogadro's Number of atoms, 6.023 times 10 to the 23rd power or 6.023E23, where "E" stands for "10 raised to the power of". So, 1.11 mole would be greater.
Where does the word mol come from in chemistry?
One "mole" of any element or compound is one "Avogadro's Number" of atoms or molecules; 6.023 times 10 to the 23rd power.
What is 6.0210 to the 23rd power molecules?
Avagadros number - The number of molecules/element that are found in one mole of the substance
What is 6.022 times 10 to the 23rd power?
6.022 x 10^(23) is the Avogadro Number. It is the number of atoms/molecules in ONE mole of a substance. Named after 'Amadeus Avogadro' an historical Italian Chemist/Scientist.
How many atoms of gold in one mole of gold?
6.02*10(to the 23rd)
How many moles of gold are in 1.20 times 10 to the 24th atoms of gold?
Using avagadro's number of 6.022 x 10 to the 23rd atoms/mole. The answer is 1.99 moles of gold
What is mole determined by?
A mole, as in Chemistry, is merely a unit of measure. Saying there is a mole of something is similar to saying there is a dozen of something; it's not about size, it's about quantity. A mole uses Avagadro's number, which is roughly 6.02 x 10 to the 23rd power. that is, about 602000000000000000000000 atoms or molocules of an element is a mole of that element or compound. Another thing to note is that if you have a mole of water, for example, that means you have 2 moles of H and 1 mole of O, since there are 2 H's in water with 1 O.
How many atom are in 143g of calcium?
First, look up the atomic mass of calcium: 40.08 grams per mole 143 grams, divided by 40.08 grams per mole, results in 3.57 moles. Since you specifically asked for the number of ATOMS, multiply by Avogadro's number, 6.02 x 10-to-the-23rd-power atoms per mole. Final answer: 2.15 x 10-to-the-24th power atoms.
Number of moles of hydrogen atoms in 10.7 mol water?
H2O is water. One mole of water contains 2 moles of hydrogen atoms. Therefore, 10.7 moles of water contain 21.4 moles of hydrogen atom.
As the atomic masses of the elements on the periodic table increases what happens to each of the number of atoms in 1 mol of each element?
It is the same. 1 mole is always 23 6.022x10 from wikipedia under "Mole (unit)", "one mole of iron contains the same number of atoms as one mole of gold;" It is the same. 1 mole is always 6.022 x (10 to the 23rd) from wikipedia under "Mole (unit)", "one mole of iron contains the same number of atoms as one mole of gold;"
What are particles measured in?
Individual atoms are measures as units. Just count them up.If you want to know how many atoms are in a given sample, we use the mole as a way to count them.One mole is 6.02x1023 units. So if you have 2 moles of helium, you have 12.04x1023 atoms of helium.
