Calculate molality of 2.5 g of ethanoic acid (CH_3COOH) in 75g benzene.

Calculate molality of 2.5 g of ethanoic acid in 25g of benzene

Benzene melts at 5.50^(@)C and has a freezing point depression constant of 5.10^(@)C dot" m^(-1) . Calculate the freezing point of a solution that contains 0.0500 mole of acetic acid , CH_(3)COOH , in 125 g of benzene if acetic acid forms a dimer in this solvent :

Pure benzene freezes t 5.3^(@)C . A solution of 0.223 g of phenylacetic acid (C_(6)H_(5)CH_(2)COOH) in 4.4 g of benzene (K_(f) = 5.12 Kkg mol^(-1)) freezes at 4.47^(@)C . From the observation one can conclude that :
