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.

Question

Given 4.08 X 1023 molecules of A, the number of
moles of A is calculated as:
O 4.08*10^-23/(6.022)
O 4.08*10^23/(6.022*10^-23)
O (6.022*10^23)*4.08*10^23
O 4.08*10^23/(6.022*10^23)

What number of atoms of nitrogen are present in 1.00 g of each of the compounds in Exercise 51?
DDT (molar mass = 354.49 g/mol) was a widely used insecticide that was banned from use in the United States in 1973. This ban was brought about due to the persistence of DDT in many different ecosystems, leading to high accumulations of the substance in many birds of prey. The insecticide was shown to cause a thinning of egg shells, pushing many birds toward extinction. If a 20-L drum of DDT was spilled into a pond, resulting in a DDT concentration of 8.75 105 M, how long would it take for the levels of DDT to reach a concentration of 1.41 107 M (a level that is generally assumed safe in mammals)? Assume the decomposition of DDT is a first-order process with a half-life of 56.0 days.

Pentaerythritol tetranitrate (abbreviated PETN, chemical formula C5H8N4O12) is an explosive material with a structure that is very similar to nitroglycerin. It is one of the components of plastic explosives such as Semtex. The explosion of PETN can be represented by: C5H8N4O12(s)→2CO(g)+4H2O(g)+3CO2(g)+2N2(g) A plastic explosive charge is formed into a cylinder about 30 cm long and about 2 cm in diameter. It weighs about 276 grams and is 58.5% PETN by mass. What is the total number of moles of gas produced when this plastic explosive charge explodes?
