What is the percent composition of each of the following compounds?
(a)
Interpretation:
The percent composition of the given compound is to be determined.
Explanation of Solution
The percent composition of any substance is calculated by dividing the mass of the substance in a sample by the total mass of the sample. This ratio is multiplied by
To determine the percent composition, let the sample size be
The mass of S from the periodic table is
The mass of O from the periodic table is
Therefore, the total mass of
Now, the percent composition of S is as follows:
Now, the percent composition of O is as follows:
(b)
Interpretation:
The percent composition is to analyzed.
Explanation of Solution
To determine the percent composition, let the sample size be
The mass of Cu from the periodic table is
The mass of Cl from the periodic table is
Therefore, the total mass of
Now, the percent composition of Cu is as follows:
Now, the percent composition of Cl is as follows:
(c)
Interpretation:
The percent composition is to analyzed.
Explanation of Solution
To determine the percent composition, let the sample size be
The mass of Na from the periodic table is
The mass of P from the periodic table is
The mass of O from the periodic table is
Therefore, the total mass of
Now, the percent composition of Na is as follows:
Now, the percent composition of P is as follows:
Now, the percent composition of O is as follows:
(d)
Interpretation:
The percent composition is to analyzed.
Explanation of Solution
To determine the percent composition, let the sample size be
The mass of Mg from the periodic table is
The mass of N from the periodic table is
The mass of O from the periodic table is
Therefore, the total mass of
Now, the percent composition of Mg is as follows:
Now, the percent composition of N is as follows:
Now, the percent composition of O is as follows:
