Acetic acid dissolved in benzene shows a molecular mass of:

Acetic acid dissolved in benzene shows a molecular mass of _____ g mol ^(-1) .

Acetic acid dissolved in benzene shows a molecular mass of _____ g mol ^(-1) .

Benzoic acid dissolved In benzene shows double of its molecular mass.Give reasons.

2g of benzoic acid dissolved in 25g of benzene shows a depression in freezing point equal to 1.62K. What is the percentage association of benzoic acid if it forms a dimer in solution ? ( K_(f) for benzene = 4.9 K kg "mol"^(-1) )
