The value of observed and calculated molecular weight of silver nitrate are $$92.64$$ and 170 respectively. The degree of dissociation of silver nitrate is :

When a solution containing non-volatile solute is diluted with water,

An ideal solution formed by mixing two liquids  'A' and 'B' find the pressure at which $${X_A} = {Y_B}\ ({P_A}^0 = 400\ torr,{P_B}^0 = 100\,torr)$$ 

An ideal solution is formed by mixing two liquids 'A' and 'B'. Find pressure at which $${X_A} = {Y_B}\,\,({P_A}^\circ  = 400\,\,torr,\,\,{P_B}^\circ  = 100\,\,torr)\,\,:\,\,({X_A}\,\,and\,\,{Y_B}$$ are mole fractions of A and B liquids and vapour forms, respectively, at equilibrium.) 

The relative lowering of vapour pressure of a solution of 6 g of urea dissolved  in 90 g of water is equal to 

Binary solute $$(AB)$$ $$60\%$$ dissociate and $$40\%$$   dimerise. Value of van't Hoff factor $$(i)$$ is 

A solution is prepared by mixing $${\text{8}}{\text{.5}}\,{\text{g}}$$ of $${\text{C}}{{\text{H}}_{\text{2}}}{\text{C}}{{\text{l}}_2}$$ and $$11.95\,{\text{g}}$$ of $${\text{CHC}}{{\text{l}}_{\text{3}}}$$. If vapour pressure of $${\text{C}}{{\text{H}}_{\text{2}}}{\text{C}}{{\text{l}}_{\text{2}}}$$ and $${\text{CHC}}{{\text{l}}_3}$$ at $${\text{298}}\,{\text{K}}$$ are $$415$$ and $$200\,{\text{mm}}$$ Hg respecetively, then mole fraction of $${\text{CHC}}{{\text{l}}_{\text{3}}}$$ in vapour form is:

The Vatn's Hoff factor for $$0.1M$$ $$Ba{({NO}_{3})}_{2}$$ solution is $$2.74$$. The degree of dissociation is:
