molekyylipainoska
Molekyylipainoska, Finnish term for a molecular weight scale, is a concept used in chemistry to describe a way of expressing and comparing the weights of molecules. It refers to a numerical convention that assigns a value to a molecule reflecting its relative molecular weight, typically expressed in daltons (Da) or in grams per mole (g/mol). In practice, the molecular weight in daltons of a compound equals its molar mass in g/mol, so the numbers on the scale are interchangeable across these two units.
The term is not an official SI unit but a pedagogical or descriptive expression common in Finnish
Calculation and examples: molecular weight is obtained by summing the atomic weights of all atoms in the
Limitations: the value depends on isotopic composition and the level of rounding; molecular weight is not a
