31 g of ethylene glycol (C_2H_6O_2) is dissolved in 600g of water. The freezing point depression of the solution is (K_f for water is 1.86 K Kg mol^-1)
1.2 mL acetic acid having density 1.06 g cm^(-3) is dissolved in 1 litre of water. The depression in freezing point observed for this concentration of acid was 0.041 ""^(@)C . The van't Hoff factor of the acid is ( K_(f) of water = 1.86 K kg mol^(-1) )
Assertion:Ethylene glycol is added to water and used as antifreeze in the radiators of auto-mobiles. Reason: Addition of ethylene glycol lowers the freezing point of water.
When a solution containing "W" g of urea in 1 kg of water is cooled to -372(@)C , 200g of ice is separated . If K_(f) for water is 1.86 K kg "mol"^(-1) . W is ___________
6 g of a non volatil, non electrolyte X dissolved in 100g of water freezes at -0.93^@C . The molar mass of X in g mol^(-1) is (K_f of H_2O=1.86kgmol^(-1)) .
12.25 g of CH_(3)CH_(2)CHCICOOH is added to 250 g of water to make a solution . If the dissociation constant of above acid is 1.44xx10^(-3) the depression in freezing point of water in ""^(@)C "is" (K_(f) for water is 1.86 K kg "mol"^(-1))
