In the determination of molar mass of A^(+) B ^(-) using a colligative property, what may be the value of van't Hoff factor if the solute is 50% dissociates ?

In the determination of molar mass of A^(+) B ^(-) using a colligative

1.	In the determination of molar mass of A^(+) B ^(-) using a colligative property, what may be the value of van't Hoff factor if the solute is 50% dissociates ?
Answer» `0.5` `1.5` `2.5` `1` SOLUTION :`ALPHA = (I -1)/( N -1) =0.5` `(i-1)/(2-1) =0.5` `I -1 =0.5` `THEREFORE I =0.5 +1=1.5`
