You can work out the molecular formula from the empirical formula, if you know the relative mass formula (M r) of the compound. Add up the atomic masses of the atoms in the empirical formula.

Physicists study this interaction on various scales, from the atomic to molecular level, in order to explore critical scientific questions. AMO physicists strive to understand and control atoms, ...

But, the mass has in fact stayed the same. Katie: What is this? Sorcery? Miss Roberts: No, it's because the tiny particles that make up stuff or the matter in an object - known as atoms - they ...

RECENT work has shown that many long-chain polymers 1,2 can be cross-linked by high-energy radiation; although polymers containing only carbon atoms in the main chain have been studied in great ...

A new toy has been added to the multitude of molecular mechanical components ... studies in which the magnetic properties of individual atoms have been probed by placing them in magnetic tunnel ...
