A decimolar solution of potassium ferrocyanide is 50% dissociated at 300K. Calculate the osmotic pressure of the solution. (R="8.314 J K"^(-1)"mol"^(-1)).

Answer»


SOLUTION :`{:(K_(4)[FE(CN)_(6)],hArr,4K^(+),+,[Fe(CN)_(6)]^(4-),),(1-alpha,,4alpha,,""alpha.,"TOTAL "=1+4alpha):}`
`i=1+4alpha=1+4xx0.5=3`
Apply `pi=iCRT`
