Final answer:
The formula for IF5 is simply IF5, representing a molecule composed of one iodine atom and five fluorine atoms. This is a covalent substance formula that indicates the actual number and types of atoms in a single molecule, allowing for the calculation of molecular mass.
Step-by-step explanation:
The actual formula for a covalently bonded substance of IF5 is simply IF5. This formula indicates the molecule is made up of one iodine atom and five fluorine atoms. Covalent substances have molecular formulas that show the exact number of atoms of each element in a molecule. In the case of IF5, this is a molecular compound also known as iodine pentafluoride, which is used for various purposes including as a fluorinating agent in organic synthesis.
The molecular mass of IF5 can be calculated by adding the atomic masses of one iodine atom and five fluorine atoms, similar to how the molecular mass of chloroform (CHCl3) is calculated. Understanding the representation of molecular formulas and determining molecular masses is essential when working with covalent compounds. In examples like CHCl3 and IF5, the atomic composition directly reveals how the molecules are structured, which is vital for interpreting chemical properties and reactions.
