Relative formula mass

• A compound's relative formula mass can be found using its chemical formula, which shows how many atoms of each element are present in one molecule.
• The relative formula mass is calculated by adding up all the relative atomic masses of the atoms present in one molecule.
• Relative Formula Mass = Sum of the relative atomic masses
• The relative formula mass is calculated by adding up the atomic masses of all the elements in the formula multiplied by their coefficients.
• The masses of substances made from 2 or more atoms can also be compared to the mass of carbon-12
• Relative formula mass is the mean mass of a unit of a substance compared to 1/12 of the mass of a carbon 12 atom
