Question

The specific conductance of N/10 KCl at 25°C is 0.0112 ohm^-1 cm^-1.The resistance of cell containing solution at the same temperature  was found to be 55 ohm. The cell constant will be

(a) 6.16 cm^-1

(b) 0.616 cm^-1

(c)  0.0616 cm^-1

(d) 616 cm^-1

Answer 1

Correct option (b) 0.616 cm^-1

Explanation:

We know that,

Specific conductance = Cell constant x Conductance

= Cell constant = Resitance x sp. conductance

= 55 x 0.0112 = 0.616 cm^-1
