As we learned 

 

Mathematical Expression -

\Delta T_{b}= K_{b}\: m

Unis of K_{b}=\frac{K-K_{g}}{mole}

\Delta T_{b}= Elevation\: in \: boiling\: point
 

- wherein

K_{b}= Boiling \: point \: elevation \: constant

m= molality

 

 K_{b}=\frac{\Delta T_{b}}{m}=\frac{0.1\times 100}{\frac{1.8}{180}\times 1000}=1K/m

 


Option 1)

0.01 K / m

Option 2)

0.1K/m

Option 3)

1K/m

Option 4)

10K/m
