The freezing point of nitrobenzene is `3^(@)C`. When 1.2 g of chloroform (mol. Wt. =120) is dissolved in 100 g of nitrobenzene, freezing point will be `2.3^(@)C`. When 0.6 g of acetic acid is dissolved in 100 g of nitrobenzene, freezing point of solution is `2.64^(@)C`. If the formula of acetic acid is `(CH_(2)O)_(n)`, find the value of n.
