Combustion of hydrocarbons like methane CH4 produce two products, water and carbon dioxide CO2. Notice that the labels changed from molecules to moles. This does not change the mole ratio, as a mole is simply a large number of molecules.  Complete the table below: mol CH4 mol O2 mol CO2 mol H2O Excess mol CH4 Excess mol O2                                     (32) (33) 3 mol (34) 7 mol 1 mol

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.
