Or relative molar mass.
"Molecular weight (M.W.) and formula weight (F.W.) are older terms for what is now more correctly called the relative molar mass (Mr). This is a dimensionless quantity (i.e., a pure number, without units) equal to the molar mass divided by the molar mass constant."
Berkeley review says that it is empirical weight. I want to confirm because confusing wiki definition. thanks.
