Problem 75E

An element has two naturally occurring isotopes. Isotope 1 has a mass of 120.9038 amu and a relative abundance of 57.4%, and isotope 2 has a mass of 122.9042 amu. Find the atomic mass of this element and identify it.

Step-by-Step Solution:

Solution : Step 1: In this problem, we are supposed to give the name or chemical formulas for the given acids. So let’s see what is an acid and then we will look into rules for naming acids and for writing chemical formulas and then we would write the formulas and name depending upon the compounds given. Step 2: Acids are chemical agents that release hydrogen ions when added to water. Hence all acids contain Hydrogen. The pH scale is a scale that is used to represent the level of acidity in a solution. A solution with a pH of 7 is neutral, while a solution with a pH below 7 is an acid, and a solution with a pH above 7 is a base. Considering the nomenclature of acids, naming an acid mainly depend on the name of the acid's anion : Naming acids that doesn’t contain oxygen in the anion: Here, the acid name comes from the root name of the anion name. Acids containing anions whose names end in -ide are named by changing the suffix -ide to -ic and adding the prefix hydro- to this anion name, and then following with the word a cid. Naming acids that contain oxygen in the anion(Oxoacids): Acids that contain oxygen atoms in the anions are called oxoacids. Here, the acid name comes from the root name of the oxyanion name. These acids have hydrogen, a nonmetal, and may have varying numbers of oxygen atoms. Acids containing oxyanions whose names end in -ate or -ite are named by changing -ate to -ic and -ite to -ous and then adding the word acid. Prefixes in the oxyanion name are retained in the name of the acid. The acid with o ne more oxygen than the -ic acid is prefixed with per-. The acid with one less oxygen than the -ic acid is suffixed with -ous acid. If the acid has one less oxygen than the - ous acid, it is prefixed with hypo- and suffixed with -ous acid.
