Gas stoves are powered by the combustion of propane (C3H8). The combustion reaction of propane is shown in the following equation. C3H8 (g) + 5 O2 (g) → 3 CO2 (g) + 4 H2O (g) Say you are carrying out this reaction on a smaller scale in a laboratory setting. You begin with two sealed containers: one with propane (325 mL, 79℃, 672 torr), and another with oxygen (1,637 mL, 83.5℃, 698 torr).

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.
