45 g of ethylene glycol (C_(2)H_(6)O_(2)) is mixed with 600 g of water. Calculate (a) the freezing point depression and (b) the freezing point of the solution.
The molal freezing point constant for water is 1.86 K . Kg "mole"^(-1) . The freezing point of 0.1 m NaCl solution is
Two elements A and B from compounds having formula "AB"_(2) and "AB"_(4) . When dissolved in 20g of Benzene (C_(6)H_(6)) , 1g of "AB"_(2) lowers the freezing point by 2.3 K whereas 1.0g of "AB"_(4) lowers it by 1.3 K. The molar depression constant for benzene is 5.1 K kg "mol"^(-1) . Calculate atomic masses of A and B.
The freezing point of 0.2 molal solution of acetic acid in benzene is 277.65 . Freezing point of pure benzene is 278.4 K and heat of fusion of benzene is 10.04 Kj//"mol" . If molarity of solution is equal to molality , and acetic acid is found in equilibrium with its dimmer, then answer the following based on this data The degree of association of acetic acid should be
The boiling point of an aqueous solution is found to be 100.28^(@)C . Then the freezing point of the same solution is -X^(0)C . What is the value of 'X' ?
1.0 g of a non-electrolyte solute (molar mass 250 g "mol"^(-1) ) was dissolved in 51.2 g of benzene. If the freezing point depression constant of benzene is 5.12 K kg "mol"^(-1) , the lowering in freezing point will be
