Benzene has been used as a solvent for waxes and oils.In 1981 the EPA listed benzene as a carcinogen.What is the molecular formula of benzene if the empirical formula is C1H1,and the approximate molar mass is 78 g/mol?

Question

Quizplus · Accepted Answer

The empirical formula indicates that benzene consists of one carbon atom and one hydrogen atom. However, the approximate molar mass of 78 g/mol suggests a molecular formula that is a multiple of the empirical formula. The molecular formula of benzene is actually C6H6, which has a molar mass of 78 g/mol.
