Formula units / molecules
2 days ago · The difference is such that the number of molecules is the actual number in the present problem, meaning it is the actual outcome from the equation. Formula units are the smallest ratio derived from the actual number of molecules. An example would be such that there are 6 NaCl (the number of molecules) and its formula unit would just be NaCl.

In the case of the giant covalent compounds the simplest ratio of atoms withn the structure is considered to be the "formula unit". 1 mole of silicon dioxide means 1 mole of silicon dioxide formula units.
How Do You Convert Moles to Formula Units?
To convert moles of a chemical substance to formula units, first convert moles into grams by using the molar masses of the elements that form the chemical compound. Every element in a chemical substance has its own molar mass, which is measured in grams.
Molecular Weight of some Common Substances
The molecular weight of a substance, also called the molar mass, M, is the mass of 1 mole of that substance, given in M gram.. In the SI system the unit of M is [kg/kmol] and in the English system the unit is [lb/lbmol], while in the cgs system the unit of M is [g/mol].

Formula Mass and Mole Concepts of Compounds | Protocol
The mass of all molecules (or formula units) present in one mole of a chemical compound is called its molar mass, measured in g/mol. The molar mass of a compound is numerically equal to its molecular mass (or formula mass). For example, sucrose, with molecular mass of amu, will have a molar mass of g/mol.

Ideal Gas Law with Density
One modified form of the Ideal Gas equation is to involve the density (d) and molecular weight (M) instead of volume (V) and moles (n). The mathematical form of the Ideal Gas Law is: R ideal gas constant. If the units of P, V, n and T are atm, L, mol and K, respectively, the value of R is L x atm / K x mol or J / K x mol.
