In order to go from moles to number of particles in any substance you simply multiply the number of moles by Avagadro's number (6.02 x 10^23). Once you have the number of molecules (in general it's particles), you would multiply the number of molecules by the number of atoms in each molecule. In water there are 3 atoms per molecule (2 hydrogens, 1 oxygen),so you'd mulitply by 3.
Summarizing: You have to multiply the number of water moles by Avagadro's number (6.02 x 10^23) and then again by number of atoms per molecule (3).
n timesA times 3 = number of atoms in 'x' moles of water
One mole of any substance contains 6.022x10 to the power of 23 molecules of that substance. A water molecule contains two hydrogen atoms so one molecule of water has 12.044x10 to 23 hydrogen atoms.
There are the same number of atoms in one mole of beryllium as there are in one mole of magnesium :)
the chemical formula of water is H2O, so 2 hydrogen atoms and 1 oxygen atoms. if you have 1 mole of oxygen atoms (O2) and 2 mole of hydrogen atoms (H2) in a test tube then you will form 2 mole of water. uses avagadros number and the mole formula to find out how much of each substance you will form.
You divide the number of atoms by avagadro's number. Avagadro's number is 6.022x10^23 atoms/molecules / mole. The best way to remember this is by the units, atoms in each mole.
Number of nitrogen atoms in 1 mole nitrogen dioxide? Nitrogen dioxide has 1 N atom and 2 O atoms. One mole of nitrogen dioxide has 1 mole of N atoms

False, They contain the same number of molecules, not the same number of atoms. H2O contains 3 atoms, so in 1 mole of water there are 6.022*10^23 * 3 = 1.81*10^24 atoms. CH4 contains 5 atoms, so in 1 mole of methane there are 6.022*10^23 * 5 =3.01*10^24 atoms.

The number of elementary entities in a mole of the substance. The elementary entities depends on the particles making up the substance. For example, argon is made of single atoms, so a mole of argon simply contains Avogadro's number of atoms. Water, on the other hand, is made of molecules, so a mole of water contains Avogadro's number of molecules. Now each water molecule, H2O, contains 3 atoms so a mole of water contains 3xAvogadro's number of atoms. Sodium chloride, NaCl, is made of sodium and chloride ions, in a ratio of 1:1. So a mole of sodium chloride contains Avogadro's number of sodium ions, and Avogadro's number of chloride ions. A mole of sodium chloride therefore contains 2xAvogadro's number of ions in total. The number comes from the number of carbon atoms in 12g of carbon-12.
A mole is an Avagadro number of atoms - 6.022 x 10-19
The number of atoms in one mole is the number of Avogadro: 6,022 140 857.10e23.
You divide the number of atoms by avagadro's number. Avagadro's number is 6.022x10^23 atoms/molecules / mole. The best way to remember this is by the units, atoms in each mole.
As in number? No of atoms = avagadros number (6.02X10^23) times number of mole of atoms
Number of nitrogen atoms in 1 mole nitrogen dioxide? Nitrogen dioxide has 1 N atom and 2 O atoms. One mole of nitrogen dioxide has 1 mole of N atoms
There ia 6.02 x 10^23 molecules of water in one mole of water. There are three atoms in one molecule of H2O (two hydrogen and one oxygen) So there are 18.12x10^23 atoms in a mole of water molecules
The number of atoms in 0.40 mole of ANY element or compound is: 0.40 mol x 6.022x1023 atoms/mol = 2.4x1023 atoms.
