Answer:
C₆H₆
Explanation:
From the question given above, the following data were obtained:
Empirical formula = CH
Molar mass of compound = 78 g/mol
Molecular formula =?
The formula of the compound can be obtained as follow:
Molecular formula = n × Empirical formula
Molecular formula = ₙ[CH]
n[CH] = 78
n[12 + 2] = 78
14n = 78
Divide both side by side 14
n = 78/14
n = 6
Molecular formula = ₙ[CH]
Molecular formula = ₆[CH]
Molecular formula = C₆H₆
Thus, the molecular formula of the compound is C₆H₆
