What is a mole?
Keywords:
  • molecules: A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge. (1)
  • Relative formula Mass: A total of all the atomic mass values for all the atoms in a formula. (1)
  • Mole: A measure of a chemical amount. (1)

Chemical amounts are measured in moles. The symbol for the unit mole is mol. (HT only) Chemical amounts are measured in moles. What is the symbol of the unit for moles?

Define one mole in terms of Mr and Ar Calculate the number of moles in a substance using the relative formula mass. Extended writing: write instructions to another student how to calculate the number of moles using the relative formula mass Measure out and compare 1 mole of elements like iron, sulfur, magnesium, copper, aluminium and so on. Measure out and compare one mole of common compounds, water, sodium chloride, calcium carbonate and so on. YouTube: What is a mole? Avogadro’s number – The mole
How the mass of one mole of a substance calculated. (HT only)How can we calculate the mass of one mole of a substance?
One mole of a substance contains the same number of the stated particles, atoms, molecules or ions as one mole of any other substance. (HT only)If you have one mole each of two different substances, what will they share in common?
The number of atoms, molecules or ions in a mole of a given substance is the Avogadro constant. (HT only)What does Avogadro's constant represent?
The value of the Avogadro constant is 6.02 x 1023 per mole. (HT only)What is the value of Avogadro's constant?
Students should understand that the measurement of amounts in moles can apply to atoms, molecules, ions, electrons, formulae and equations, for example that in one mole of carbon (C) the number of atoms is the same as the number of molecules in one mole of carbon dioxide (CO2). (HT only)Would there be any difference in the number of atoms in one mole of carbon (C) compared with the number of one mole of molecules of carbon dioxide (CO2)?
Students should be able to use the relative formula mass of a substance to calculate the number of moles in a given mass of that substance and vice versa. (HT only)Calculate the mass of one mole of C2H6
