the SI base unit used to measure the amount of a substance

number of representative particles in a mole, 6.02 X 10^23

number of moles = mass/Mr

the sum of the relative atomic masses of the atoms in the molecular formula

actual yield/theoretical yield x 100

The weighted mean mass of an atom of an element relative to 1/12th of the mass of an atom of carbon-12

a formula with the lowest whole-number ratio of elements in a compound

A chemical formula that shows the number and kinds of atoms in a molecule, but not the arrangement of the atoms.

the maximum amount of product that can be produced from a given amount of reactant

the measured amount of a product obtained from a reaction

mol/dm3 or g/dm3

concentration =number of moles/volume

number of moles = volume/ 24

a conversion factor derived from the coefficients of a balanced chemical equation interpreted in terms of moles

The masses of elements and compounds which take part in a chemical reaction.

a principle stating that mass cannot be created or destroyed.
