Question
**Educational Content on Chemical Compounds** **Molecular Structure Diagram:** The image depicts a molecular structure consisting of two elements: Aluminum (Al) and Bromine (Br). Aluminum is centrally located, bonded to three bromine atoms in a trigonal planar configuration, indicating that the likely molecular formula involves one aluminum atom bonded to three bromine atoms. --- **Questions:** A) What is the molecular formula for this compound? **Answer:** ________________ B) What is the empirical formula for this compound? **Answer:** ________________ C) Determine the mass percentage of Al in this compound. **Answer:** ________________ --- **Explanation:** - **Molecular Formula**: This represents the actual number of atoms of each element in a molecule of the compound. - **Empirical Formula**: This gives the simplest whole-number ratio of atoms of each element in the compound. - **Mass Percentage Calculation**: This involves determining the mass of aluminum in the compound relative to the total mass of the compound, typically expressed as a percentage. The molecular model in the diagram is crucial for visualizing the spatial arrangement of atoms and aids in understanding chemical properties and reactions.
