A chemical graph is a visual representation of a molecular complex that significantly explains its components and their coordination. In this approach atoms are identified by points called vertices that are connected by lines known as edges of graph. Several organic and inorganic substances have been recently investigated using respective visual depiction based on basic topology. Iron (III) oxide, also known as hematite, is an inorganic compound with trigonal crystal system. Main objective of this study is to explore Iron (III) oxide by using its chemical graph and examine its structural features and physical properties based on topological indices by developing distinct mathematical models. It is found that derived degree-based topological indices of iron (III) oxide are successfully linked with its thermodynamic properties such as heat of formation and entropy. Our objective is to explore the chemical compound iron(III) oxide by using its corresponding chemical graph and examine its structural features and physical properties based on topological indices by developing distinct mathematical models.
