BASED ON FORMULAE
7.1 - Calculation of Formula or Molecular Mass
5.1.3, we learned about formula units. The sum of the atomic masses of all
the atoms which make up the compound is known as theformula
mass of a compound. Formula mass is a general term applied to the mass of
a substance based on summing up the atomic masses of the atoms in the chemical
formula regardless of the type of bonding between atoms in the chemical formula.
If the substance has covalent
bonding (section 5.2), we can
specifically refer to the sum of the atomic masses of all the atoms which make
up the compound the molecular
Here is how you determine the formula mass of a compound.
