The formula unit for calcium is a single atom. Therefore, the number of moles may be found by dividing the given number of atoms by Avogadro's number, or 1.999 moles.
The formula given shows that each formula unit or mole contains one calcium atom; therefore, 2.5 moles of calcium chloride contains 2.5 moles of calcium atoms.
4.0 X Avogadro's Number or 2.4 X 1024. (Elemental sodium does not technically have "moles", but its formula mass is considered to be that of a single atom.)
Add the atomic weights of one C atom and two O atoms.That's the number of grams in one mole.Use division to find the number of moles in your 211 g.
6.228 mole of zinc atom
The number of moles is 18.56.
0,17 moles of stronium is equal to 1,02376394569.10e23 atoms.
The number of moles of calcium carbonate are 3.5 moles. , there are 1 mole of calcium (Ca) atom, 1 mole of carbon (C) atom and 3 moles of oxygen (O) atoms.
The answer is 1/12,044.10e23.
0,688 g calcium is equivalent to 0,017 moles.

3.24 X 10^23 atom Ba (1mol Ba/6.022 X 10^23 ) = 0.538 moles
Every formula unit of sodium chloride has one sodium atom. Therefore, there are 4.0 moles of sodium ions in 4.0 moles of NaCl.
1 atom-gram of uranium = 238,02891 grams
Ten million atoms / Avagadro's Number, 6.022e23 atoms per mole = 1.66e-17 moles
