The specific conductivity of N/10KCl solution at 20°C is 0.0212 ohm-1 cm-1 and the resistance of cell containing this solution at 20°C is 55 ohm. The cell constant is
(a) 2.173 cm-1
(b) 1.166 cm-1
(c) 4.616 cm-1
(d) 3.324 cm-1
Correct option (b) 1.166 cm-1
Explanation:
We know that,
Specific conductance: Cell constant x Conductance
= Cell constant: Resistance x specific conductance
= 0.0212 x 55 = 1.166 cm-1
