QUIZ- Avigadro's number

An animal

6.02 x10^23 atoms

A gram of an element

Avigadro's constant or number is the number of atoms in a mole; 6.02 x10^23

How different matter is created: atoms ---> molecules ---> bulk compound atoms ---> bulk element atoms ---> ions ---> bulk ionic compound

How elements are structured in different temperatures

Relative atomic mass; the ratio of the average mass per atom of the naturally occurring form of an element to one-twelfth the mass of an atom of carbon-12. RAM is averaged over the different isotopes.

Molecular mass is the total mass of all the molar masses of atoms in a molecule

Molecular mass is the mass of a molecule of CO2

Molecular mass is the mass of one atom in a mole

Atomic Mass Units make up the Relative Atomic Mass

Relative Atomic Mass is the average mass of an element, when considering all its isotopes. Atomic Mass Unit is one twelfth of a carbon atom.

Relative Atomic Mass is the Atomic Mass Unit divided by the number of atoms involved

Moles= Total Mass/ Molecular Mass

Moles= Total Mass/ Relative Atomic Mass

Moles = Total Mass/ 6.02x10^23
