2 g of benzoic acid C6H5COOH dissolved in 25 g of benzene shows a depression in freezing point equal to 1.62 K. Molal depression constant for benzene is 4.9 K kg mol−1. What is the percentage association of acid if it forms dimer in solution?

by

WB​=2g, Kf​=4.9K Kgmol−1 WA​=25g, ΔTf​=1.62K now  If x is the degree of association, (1−x) mole of benzoic acid left undissociated & corresponding x/2 as associated moles of C6​H5​COOH at equilibrium. i = Normal molecular mass / Abnormal molecular mass 1-x/2 = 122/241.98 x=0.992 = 99.2%
