1.17 understand the use of the term mole to represent the amount of substance
A mole is an amount, in the same way that you can have a dozen buns, you can have a mole of carbon.
Having a mole of something is having 6.022x1023 of it.
n.b the 1023 thing is meant to be 10 to the power of 23.
Not quite, the dozen thing was to say that its a name for a number. So 1 carbon atom is a fraction of a mole: 1/6.022x10(23). If you had 6.022x10(23) carbon atoms, then you would have one mole.
A mole is a name given to represent an amount of substance; 1 mole = 6.02x10^23 particles (Avogadro’s number - the term mole is the Avogadro number of particles (atoms, molecules, formulae, ions or electrons) in a substance). Abbreviated to mol.
The RAM of any element in grams contains 1 mol of atoms of that element. (For example, 12g of carbon = 1 mol).
The Mr of a compound in grams contains 1 mol of that compound. (For example, 18g of water = 1 mol, Mr of water is 16+1+1)

ReplyDeleteSo are there 12 moles in 1 carbon atom?
