(a)

Explanation of Solution
The given
(b)
Interpretation:
The diatomic compound
The number of different types of
(b)

Explanation of Solution
There are four isotopic combinations:
The sum of the mass numbers is:
Using the sum of the mass numbers as a criterion, there are three types: 114, 116 and 118.
(c)
Interpretation:
The diatomic compound
The most abundant type in (b) has to be determined.
(c)

Explanation of Solution
Abundance of the diatomic molecule is determined by combining the percents.
Because there are two different isotopic combinations composing the 116 type, the abundance of this type comes from two combinations
The total abundance of the type is
The most abundant type is 116 type.
(d)
Interpretation:
The diatomic compound
The second most abundant has to be determined.
(d)

Explanation of Solution
Abundance of the diatomic molecule is determined by combining the percents.
Because there are two different isotopic combinations composing the 116 type, the abundance of this type comes from two combinations
The abundance of the 1174 type is
The second most abundant type is 114 type.
