$\begin{array}{rl}& \Delta {\mathrm{T}}_{\mathrm{b}}={\mathrm{K}}_{\mathrm{b}}\cdot \mathrm{m}\\ & {\mathrm{T}}_{\mathrm{b}}-{\mathrm{T}}_{\mathrm{b}}^{\circ }={\mathrm{K}}_{\mathrm{b}}\cdot \mathrm{m}\\ & {\mathrm{T}}_{\mathrm{b}}-100^{\circ }\mathrm{C}={\mathrm{K}}_{\mathrm{b}}\times 0.5\\ & 100.16-100^{\circ }\mathrm{C}={\mathrm{K}}_{\mathrm{b}}\times 0.1\\ & {\mathrm{K}}_{\mathrm{b}}=\frac{0.16}{0.1}=1.6\text{ (From equation }2)\\ & {\mathrm{T}}_{\mathrm{b}}-100^{\circ }\mathrm{C}=1.6\times 0.5\\ & {\mathrm{T}}_{\mathrm{b}}=100+0.80=100.80^{\circ }\mathrm{C}\end{array}$
