When converting the mols measurement into atomic weight (or vice-versa). Since there are 6.02x10^26 atoms in a mol.
There are some keywords you can look for to determine whether or not you need to use Avogadro's number. Look for the keywords ions, molecules, moles (IF grams [g] to moles), and formula units in the question. If the question is asking for any of these terms or involves any of those terms, Avogadro's number will be necessary to use.
atoms in 12 g of c-12
The unit is "per mole", or mol^-1.
Avogadro's number represents the number of units of a substance in one mole of the substance. These units may be electrons, atoms, ions, or molecules, depending on the substance.
A mole of any substance has the Avogadro's number of such units. As an example, a mole of hydrogen atoms is equivalent to 6.022 x 1023 atoms.
By saying Avogadro's number of atoms, you are saying one mole (or 6.02 × 1023 atoms). And one mole of any elements is its atomic mass. Phosphorus' atomic mass is 31.0 grams
A mole.
No.
Its avogadros number
I asked this question wrong. It should be Avogadros Number. Sorry!
atoms in 12 g of c-12
It is 6.02 (times) 10 to the power of 23
The unit is "per mole", or mol^-1.
It is the number of fundamental particles - atoms or molecules - of a substance in 1 mole of that substance.
There is 1 mole of atoms in 6.022 x 10^23 atoms of any element.
To find the number of atoms in 55.8 grams of Fe, you need to first calculate the moles of Fe using the molar mass (55.85 g/mol). Then you can use Avogadro's number (6.022 x 10^23) to convert moles to atoms.
Its avogadros number which is 6.02 X 10^23 g/mol
Avogadro's number represents the number of units of a substance in one mole of the substance. These units may be electrons, atoms, ions, or molecules, depending on the substance.
