Chemistry : Molecular Weights of Chemical Compounds
How to Calculate the Molecular Weight of a Chemical Compound?
The Molecular Weight (also referred to as the Formula Weight) of a chemical compound is calculated by adding the atomic weights of the atoms (elements) that constitute the compound.
Molecular weight of Na2CO3
Note that the Atomic Weight (also referred to as the Relative Atomic Mass) of an element is the number of times an atom of an element is heavier than an atom of hydrogen. Thus, hydrogen is treated as the reference, whose atomic weight is taken as 1.
