Molecular+vs+Empirical+Formulas

=Molecular vs. Empirical Formulas=

Molecular formulas indicate the actual numbers and types of atoms in a molecule. They provide more information about molecules than empirical formulas (Brown, LeMay, Bursten).

Empirical formulas give only the relative numbers of atoms of each type in a molecule. The subscripts are the smallest and most simplified whole-number ratios (Brown, LeMay, Bursten).

Examples:


 * Empirical Formula || Molecular Formula ||
 * AlBr3 || Al2Br6 ||
 * C4H5 || C8H10 ||
 * C3H4O || C4H8O2 ||
 * P2O5 || P4O10 ||
 * C3H2Cl || C6H4Cl2 ||
 * BNH2 || B3N3H6 ||

How to change molecular to empirical formula
Step 1:// Molecular Formula = C6H12O6 //Step 2:// All subscripts are divisible by 6. //Step 3:// Empirical Formula = CH2O **
 * //Glucose
