==Key Stage 4==
===Meaning===
The '''relative formula mass''' ('''M<sub>r</sub>) of a [[molecule]] is the [[mass]] of one [[mole]] of the [[molecule]].
===About Relative Formula Mass===
: '''Relative formula mass''' can be calculated from the [[Chemical Formula|chemical formula]] of the [[molecule]] and the [[Relative Atomic Mass|relative atomic mass]] of the [[element]]s.
: The '''relative formula mass''' is used to find the [[mass]] of a [[molecule]] needed to perform a complete [[Chemical Reaction|reaction]] with another [[chemical]].
