  • A solution with conductivity    having resistance of  <img alt="5.81 \Omega" src=

A solution with conductivity  0.41 \mathrm{sm^{-1}}  having resistance of  5.81 \Omega in a conductivity cell. If same cell is filled with another solution, the resistivity drops to 1.97 \Omega . What is conductivity of new solution?

Option: 1

3.4 \mathrm{sm}^{-1} \\


Option: 2

2.8 \mathrm{sm}^{-1} \\


Option: 3

0.6 \mathrm{sm}^{-1} \\


Option: 4

1.2 \mathrm{sm}^{-1}

\mathrm{K=\frac{1}{R} G^*} 
for same Conductivity \mathrm{ G^*}  is constant

\mathrm{0.41 \times 5.81=k \times 1.97 \\ }

\mathrm{k=\frac{0.41 \times 5.81}{1.97} \\ }

\mathrm{K=1.2 \mathrm{sm}^{-1} }.
