Question

The cell constant of a given cell is $0.47c{m}^{-1}$. The resistance of a solution placed in this cell is measured to be $31.6ohm$. The conductivity of the solution (in $Sc{m}^{-1}$ where $S$ has usual meaning) is :

• A. $0.15$
• B. $1.5$
• C. $0.015$
• D. $150$

Answer 1

The correct option is C $0.015$

$Conductivity,k=\frac{1}{R}\times \text{Cell constant}=\frac{0.47}{31.6}=0.01487\approx 0.015$

Hence, option C is correct.
