The resistance of conductivity cell containing 0.01 M KCl solution at 298 K is 1750 $\mathrm{\Omega }$. If the
conductively of 0.01 M KCl solution at 298 K is $0.152\times {10}^{-3} \mathrm{S}{ \mathrm{cm}}^{-1}$, then the cell constant of the conductivity cell is______________ $\times {10}^{-3}{ \mathrm{cm}}^{-1}$
