(a)
Answer to Problem 1.87EP
In the given mixture of five molecules, two kinds of molecules contains four or fewer atoms in it.
Explanation of Solution
Given molecules in mixture are
Number of atoms in
Number of atoms in
Number of atoms in
Number of atoms in
Number of atoms in
From the above number of atoms present in each and every molecule, the atoms that contains four or fewer atoms are
(b)
Interpretation:
The different kind of atoms that is present in the mixture has to be given.
Concept Introduction:
The composition of a chemical compound can be presented in a very precise was with the use of chemical formula. Chemical formula uses chemical symbols of the elements that is present in the compound and numerical subscripts that represent how many number of atoms of each element is present in the compound.
(b)
Answer to Problem 1.87EP
Four kinds of atoms are present in the mixture.
Explanation of Solution
Given molecules in mixture are
Looking into the molecules in the given mixture, it is found that there are four kind of atoms present in the given molecules and they are
(c)
Interpretation:
The total number of atoms that is present in the mixture that contains five molecules of each component has to be given.

(c)
Answer to Problem 1.87EP
There are a total of 110 atoms present.
Explanation of Solution
Given molecules in mixture are
Number of atoms in
Number of atoms in
Number of atoms in
Number of atoms in
Number of atoms in
The total number of atoms that is present in mixture which contains one molecule of each component can be found by summing up the number of atoms in all molecules. This gives the total number of atoms as 22.
If the mixture contains five molecules of each component, then the total number of atoms can be found as shown below,
Therefore, there are 110 atoms present in the mixture that contains five molecules of each component.
(d)
Interpretation:
The total number of hydrogen atoms that is present in the mixture that contains four molecules of each component has to be given.

(d)
Answer to Problem 1.87EP
There are a total of 56 hydrogen atoms present.
Explanation of Solution
Given molecules in mixture are
Number of atoms in
Number of atoms in
Number of atoms in
Number of atoms in
Number of atoms in
The total number of hydrogen atoms that is present in mixture which contains one molecule of each component can be found by summing up the number of hydrogen atoms in all molecules. This gives the total number of hydrogen atoms as 14.
If the mixture contains four molecules of each component, then the total number of hydrogen atoms can be found as shown below,
Therefore, there are 56 hydrogen atoms present in the mixture that contains four molecules of each component.
