The symbol for the unit mole is mol and the mass of one mole of a substance in grams is numerically equal to its relative formula mass (can be atomic mass or molecular mass - see below). This might be an atomic mass of an element e.g. Fe = 56, so 1 mol = 56g
A relative formula mass (or M r for short) tells us the total mass of all the particles found in each formula of a substance. To be able to calculate the M r we need to know the mass of the individual particles, which is called the relative atomic mass (or A r for short). The A r of each atom can be found using the periodic table.
