?The molar mass of benzoic acid \(\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{COOH}\)
Chapter 12, Problem 61P(choose chapter or problem)
The molar mass of benzoic acid \(\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{COOH}\) determined by measuring the freezing-point depression in benzene is twice what we would expect for the molecular formula \(\mathrm{C}_{7} \mathrm{H}_{6} \mathrm{O}_{2}\). Explain this apparent anomaly.
