TERACTIVE EXAMPLE Calculating the Molar Mass of a Gas from P, V, and T Data You are trying to determine, by experiment, the formula of a gaseous hydrofluorocarbon compound you made to replace chlorofluorocarbons in air conditioners. You have determined the empirical formula is CHF₂, but now you want to know the molecular formula. You therefore do an experiment to determine its molar mass and find that a 0.100-g sample of the compound exerts a pressure of 73.5 mm Hg in a 247-ml container at 23.0 °C. What is the molar mass of the compound? What is its molecular formula? Enter the elements of the formula in the order C, H, F. g/mol Molecular formula-

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
