Resistance of 0.1M NaCl aqueous solution at 298K is 50 ohm . What is the value of conductance of this solution?

Correct option is D

The correct answer is (D) 0.02 S

The conductance (G) is the reciprocal of the resistance (R).
Given that the resistance $$R = 50 \, \Omega, \text{the conductance}\ G = \frac{1}{R} = \frac{1}{50} = 0.02 \, S.$$​​

1. Conductance (G) is the inverse of resistance (R).

2. Conductance is measured in Siemens (S).

3. The formula for conductance is

   $$G =\frac{1}{R} ​$$​

4. The given value of resistance (50 ohms) directly gives the conductance when inverted.

5. This relationship applies to ionic solutions like NaCl in water.
