- Formula mass and mole calculations
- chemists measure the amount of a substance in moles
- one mole of carbon atoms is 12 g
- one mole of compound is 6*10^23
- The relative atomic mass of an element shows its mass compared with the mass of atoms of other elements.
- Relative atomic masses can be used to find the relative formula massof a compound.
- The relative formula mass of a substance, shown in grams, is called one mole of that substance.
- Chemists measure the amount of a substance in a unit called ‘the mole’. This is a convenient way of counting atoms. It allows chemists to make predictions about the masses of different substances that are involved in reactions.
