Answer:
The relative formula mass of a substance made up of molecules is the sum of the relative atomic masses of the atoms in the numbers shown in the formula . Relative formula mass has the symbol, M r. To calculate the M r for a substance: work out how many atoms of each element there are in the chemical formula.
Relative abundances of isotopes are often given as percentages. To work out the relative atomic mass of an element, all you need to do is multiply each isotopic mass by its relative abundance, add all the values together and divide by 100.
