\(\Delta {{\text{T}}_{\text{b}}}{\text{  =  i }} \times {\text{ kb }} \times {\text{ m}}\,\) ( ગ્લુકોઝ માટે \({\text{i  =  1}}\))

\({\text{ }}\Delta {{\text{T}}_{\text{b}}}{\text{  =  }}{{\text{K}}_{\text{b}}}{\text{ }} \times {\text{ m}}\,\,\)

\(\,\therefore \,\,{K_b} = \frac{{\Delta T}}{m} = \frac{{0.1}}{{0.1}} = 1\frac{K}{m}\)
