a.
Interpretation:
The empirical formula that corresponds to each of the molecular formula of sodium peroxide needs to be determined.
Concept Introduction:
A molecular formula tells the actual number of atoms percent in the molecule or compound. The empirical formula is the simplest ratio of number of atoms in the compound.
a.

Answer to Problem 33A
Empirical formula is NaO.
Explanation of Solution
Given Sodium peroxide Na2O2
Hence, empirical formula is NaO
b.
Interpretation:
The empirical formula that corresponds to each of the molecular formula of terephthalic acid needs to be determined.
Concept Introduction:
A molecular formula tells the actual number of atoms percent in the molecule or compound. The empirical formula is the simplest ratio of number of atoms in the compound.
b.

Answer to Problem 33A
Empirical formula is C4H3O2
Explanation of Solution
Terephthalic acid C8H6O4
(where n is 2).
Hence, empirical formula is C4H3O2
C
Interpretation:
The empirical formula that corresponds to each of the molecular formula of Phenobarbital needs to be determined.
Concept Introduction:
A molecular formula tells the actual number of atoms percent in the molecule or compound. The empirical formula is the simplest ratio of number of atoms in the compound.
C

Answer to Problem 33A
empirical formula is C12H12N2O3
Explanation of Solution
Given: Phenobarbital C12H12N2O3
(here, n is one because there is no common coefficient for 12,12,2,3)
Hence, empirical formula is C12H12N2O3
d.
Interpretation:
The empirical formula that corresponds to each of the molecular formula of 1,4-dichloro-2-butene needs to be determined.
Concept Introduction:
A molecular formula tells the actual number of atoms percent in the molecule or compound. The empirical formula is the simplest ratio of number of atoms in the compound.
d.

Answer to Problem 33A
Empirical formula is =C2H3Cl
Explanation of Solution
Given:
1,4-dichloro-2-butene C4H6Cl2
Hence the empirical formula is =C2H3Cl
