Answer:
Molecular formula for benzene is C₆H₆
Explanation:
Benzene has this empirical formula → CH
Empirical weight = 13 amu
12 amu from C + 1 amu from H = 13 amu
To determine the molecular formula we can think this equation:
12 amu X, from C + 1 amu X from H = 78 amu
13 amu X = 78 amu
X = 78 amu / 13 amu = 6 → Molecular formula for benzene is C₆H₆
The empirical formula indicates what proportion of atoms there is for a given compound. Sometimes it can match the molecular formula of the compound
