2. The complete combustion of 19.0 grams of sucrose (C12H22011) was performed in a closed container with a volume of 5.0 liters. Stoichiometric amounts of oxygen were used in the combustion (meaning no limiting or excess reagent). What is the pressure inside the vessel after the combustion reaction when the temperature after the reaction is 105.0 °C? (The water is in the gas state). What will be the pressure inside the vessel if it was cooled to room temperature? (The water is in the liquid state). You must write the combustion reaction on your own.

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.
