Molecular+Formula

**Molecular Formula ** //** A molecular formula is a chemical formula of a molecular compound that shows the kinds and numbers of atoms present in a molecule of a compound. **//  **A molecular formula shows how many atoms of each element a molecule contains. A smallest whole number ratio between elements is a empirical formula. Molecular formulas refer to covalently bonded substances. It shows the exact number of aoms of each element present.**  **EXAMPLES: __Molecular Formula :__C(subscript)6 H(subscript)6 ** **__Empiricial Formula :__ C(subscript)1 H(subscript)1**

 * The molecular formula of a compound is either the same as an experimentally determined empirical formula, or it is a simple whole number multiple of its empirical formula. **

 * __The empirical formula gives the lowest whole number ratio of atoms in a compond, so when you reduce it has to be the same. The first is 1:1:4 the second is 2:2:7
