Answer:
Molecular Formula = C6H6
Explanation:
Empirical Formular = CH
Molar Mass = 78.11
Molecular Formular = ?
The Formular relating these parameters is given as;
(Empirical Formula)n = Molecular Formular
where n = Number of moles
CH = 12.0107 + 1.00784 = 13.01854
(13.01854)n = 78.11
n = 78.11 / 13.01854
n = 5.9999 ≈ 6
Molecular Formula = C6H6
Answer:
C - 12.01 g/mol
H - 1.008 g/mol
CH - 13.018g/mol
molecular formula = n×(empirical formula)
78.11 g/mol = n ×( 12.01 + 1.008) g/mol
∴ n = 5.99
≈ 6
then [tex]C_{6} H_{6}[/tex]
Explanation: First find the molar mass of the empirical formula CH.
use the formula that says: Molecular formula = n × empirical formula
therefore you divide the molar mass of the compound by molar mass of the empirical formula.
the empirical is the 6th and then multiply that 6 with the subscripts of CH.
