1.2.2 The Mole Concept
I can statements
Be able to calculate the number of particles (atoms, ions, molecules) in a specified number of moles of substance
-
Explain the term: mole (symbol ‘mol’), as the unit for amount of substance,
A mole of a substance is defined as: The mass of substance containing the same number of fundamental units as there are atoms in exactly 12.001 g of Carbon -12
Explain the term: the Avogadro constant, NA, as the number of particles per mole (6.02 × 1023 mol–1).
The number of units in one mole of any substance is called Avogadro’s number or Avogadro’s constant. It is equal to 6.022140857×1023. The units may be electrons, ions, atoms, or molecules, depending on the character of the reaction and the nature of the substance.
