Can you please help me fill out this chart? I am trying to complete my notes and I’m stuck on this part.
### Determining Molecular and Empirical Formulas When a new compound is synthesized in the lab, chemists use several characterization techniques to determine the structure and properties of the compound to prove they have made a new substance. One technique is elemental analysis which gives the mass percent of each element in the compound. With this information, the chemist can find the empirical formula for the compound, and if they know the molar mass of the compound, they can also find the molecular formula. **The Empirical Formula** is the simplest whole number ratio of atoms in a molecule. The subscripts of the empirical formula will have no common factors other than 1. **The Molecular Formula** is the actual whole number ratio of atoms in a molecule of a covalent compound. The molecular formula may be the same as the empirical formula. The formulas of ionic compounds are always empirical formulas because they represent the simplest ratio between cations and anions needed to make a neutral formula. The formulas of molecular compounds are **not** always empirical formulas because they represent how many atoms are in a molecule! Multiple molecules can have the same empirical formula. #### Tabulated Information: | Name | Ethyne (acetylene) | Benzene | Cyclohexane | Hydrogen Peroxide | |---------------------|--------------------|---------|-------------|------------------| | Molecular Formula | C₂H₂ | C₆H₆ | C₆H₁₂ | H₂O₂ | | Structural Formula (how atoms are connected to each other; lines represent bonds) | Empirical Formula | | To get the molecular formula, multiply the empirical formula by: | Note: The Structural Formula and Empirical Formula columns are empty in the provided image.
