n=Molecular massEmpirical formula mass A compound may have same empirical and molecular formulae Both these formulae are calculated by using percentage composition of constituent elements. A compound of Na, C and O contains 0.0887 mol Na, 0.132 mol O and2.65×1022atoms of carbon . the empirical...
Empirical Formula & Molecular Formula - There are two broad classes of the formula called Empirical formula & Molecular formula. The empirical formula shows the simplest ratio of elements in a compound also called simple formulas. Molecular formulas show
If the compound in question 7 has a molar mass of 431g/mol, what is the molecular formula? 2. If the compound in question 8 has a molar mass of 92g/mol, what is the molecular formula? 3. Naphthalene is a carbon and hydrogen containing compound often used in moth balls. The ...

Molecular Formula Chemical formulas were first derived by determining the masses of all the elements that combine to create a molecule, leading to the development of two important types of chemistry formulae: molecular formula and empirical formula....
It is shown that the criteria can be interpreted as extended forms of the well known chemical theorems for analysing molecular formulae, and that repeated use of the criteria identifies both functional groups and molecular fragments in a given molecular formula. We hence conclude that the ...
