Answer»

Solution :Van.t Hoff factor : Van.t Hoff introduced a factor .i. called Van.t Hoff factor, to express the EXTENT of association or dissociation in solution. It is the RATIO of normal and observed molar masses of the solute
`i=("Normal molar mass"(M_(n)))/("Observed molar mass"(M_(0)))`
In CASE of dissociation value of `i gt 1`
