What is it meant by relative formula mass? How is it calculated using the periodic table? Each element has a relative atomic mass. When a compound is made‚ these relative atomic masses are added together to calculate the relative formula mass of the substance. For example the atomic mass of Na is 23 and the atomic mass of Cl is 35.5 so the relative formula mass of NaCl is 58.5 How by using RFM is it possible to work out amounts of a substance in terms of moles? The compound I was using in my
