The simplest types of chemical formulas are called empirical formulas, which indicate the ratio of each element in the molecule. The empirical formula is the simplest whole number ratio of all the atoms in a molecule. For example: The molecular formula for glucose is C6H12O6.
What information does a molecular formula provide Shows how many atoms of each element a substance contains How is the representation unit of a molecular compound different from the representative unit of an ionic compound The representative unit of a molecule compound is a molecule. From ionic compound, the representative unit is a formula unit.
