An aqueous solution of urea had a freezing point of -0.52^(@)C. Predict the osmotic pressure of the same solution at 37^(@)C. Assume that the molar concentration and the molality are numerically equal. (K_(f)=1.86) |

Answer» Solution :MOLALITY `=(DeltaT_(F))/(K_(f))=(0.52)/(1.86)=` MOLARITY (given) Osmotic pressure `=CRT` `=(0.52)/(1.86)xx0.0821xx(273+37)` `=7.1` atm |
