PETA is also an explosive, but not as famous as TNT. Upon detonation, PETN will decompose to form different gases as shown in the following chemical equation. If 2.48 grams of PETN is detonated in a steel container, after the gases go back to room temperature (25 degrees celcius). The pressure inside the container is 28.4 atm, please estimate the total pressure immediately after explosion if the temperature was 500 degrees celcius. [Hint: the gases at 25 degrees celcius and 500 degrees celcius are different!] C(CH2ONO2)4(s) --> 2CO(g) + 4H2O(g) + 2N2(g) + 3CO2(g)

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.
