A mole of anything has Avogadro's number of objects in it. So a mole of water (H 2 O) has 6.022 x 10 23 water molecules, a mole of carbon atoms has 6.022 x 10 23 carbon atoms and a mole of automobiles (rather unlikely) would have 6.022 x 10 23 automobiles.. Clearly, if the objects we are talking about have different masses (weight), then a mole of one substance will also have a different mass. Just as one mole of atoms equals the atomic mass of an atom in grams, so also one mole of molecules equals the molar mass of the molecule in grams. Molar mass is the mass (in grams per mole) of one mole of a substance. Therefore we expect that 6.02 x 1023 molecules of water will have a mass o Second, as naturally occurring carbon contains approximately 98.90% carbon-12, the sample would need to be purified to remove every atom of carbon-13 and carbon-14. Third, as the number of particles in a mole is tied to the mass of exactly 12 grams of carbon-12, a balance would need to be constructed that could determine if the sample was one. One mole is defined as the amount of substance of a system which contains as many elementary entities as there are atoms in 12 grams of carbon-12. According to this definition, the answer is obvious. 12 grams of carbon-12 contain one mole of carbon-12 atoms. So the mass of one mole of carbon-12 is equal to 12 grams.

Explain how the mass of one mole of magnesium atoms compares to the mass of one mole of iron. The number 6.02 × 10 23 is called Avogadro's number , the number of representative particles in a mole.It is an experimentally determined number. A representative particle is the smallest unit in which a substance naturally exists. For the majority of elements, the representative particle is the atom. Iron, carbon, and helium consist of iron atoms, carbon atoms, and helium atoms, respectively A molar mass is the mass in grams per mole, that's per 6.022 times 10 to 23 of something. 6.022 times 10 to 23 is Avogadro's number. Avogadro's number is equal to the number of carbon-12 atoms. That's atoms with six protons and six neutrons in 12 grams of carbon-12

In particular, when carbon-12 was the reference, one mole of carbon-12 was exactly 12 grams of the element. These definitions meant that the value of the Avogadro number depended on the experimentally determined value of the mass (in grams) of one atom of those elements, and therefore it was known only to a limited number of decimal digits 2019 Activity B: Conversions Get the Gizmo ready: Select the CONVERSIONS tab.
