NEET 2023 Chemistry Conductivity MCQ Question
Type: MCQ-numerical-Medium-Class 12
The conductivity of centimolar solution of KCl at 25°C is 0.0210 ohm⁻¹ cm⁻¹ and the resistance of the cell containing the solution at 25°C is 60 ohm. The value of cell constant is -
A
3.28 cm⁻¹
B
1.26 cm⁻¹
C
3.34 cm⁻¹
D
1.34 cm⁻¹
Correct Answer
Option B
Detailed Explanation
Cell constant = Conductivity × Resistance = 0.0210 ohm⁻¹ cm⁻¹ × 60 ohm = 1.26 cm⁻¹.
