Concept explainers

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.

Phosgene, a substance used in poisonous gas warfare during World War I, is so named because it was first prepared by theaction of sunlight on a mixture of carbon monoxide and chlorine gases. Its name comes from the Greek words phos (light) andgenes (born of). Phosgene has the following elemental composition: 12.14% C, 16.17% O, and 71.69% Cl by mass. Its molarmass is 98.9 g>mol. (a) Determine the molecular formula of this compound. (b) Draw three Lewis structures for the moleculethat satisfy the octet rule for each atom. (The Cl and O atoms bond to C.) (c) Using formal charges, determine which Lewisstructure is the dominant one. (d) Using average bond enthalpies, estimate ΔH for the formation of gaseous phosgene fromCO(g) and Cl21g2.

Cocaine(C17H21O4N) is a natural substance found in the leaves of the coca plant, which has been used for centuries as a local anesthetic and stimulant. Illegal cocaine arrives in the USA either as a pure compound or as the hydrochloride salt(C7H21O4NHCl). At 25 degrees celsius, the salt is very soluble in water(2.59kg/L), but pure cocaine is much less so(1.70g/L) a. What is the maximum amount of salt in grams that can dissolve in 50.0mL of water? b. When a 25mL aqueous solution that contains 62.50 g of the salt is treated with NaOH, the salt is converted to pure cocaine. How much water in liters is needed additionally to dissolve the formed pure cocaine,
Lysine is an amino acid which has the following elemental composition: C, H, O, N. In one experiment, 2.175g of lysine was combusted to produce 3.94g CO2 and 1.89 H2O .
