Question

The molar conductivity of a 0.5 mol dm⁻³ solution of AgNO₃ with specific conductance 5.76 × 10⁻³ S cm⁻¹ at 298 K is:

• A. 0.086 S cm² mol⁻¹
• B. 2.88 S cm² mol⁻¹
• C. 28.8 S cm² mol⁻¹
• D. 11.52 S cm² mol⁻¹

Hint:

Always check units! If κ is given in S m⁻¹, the formula changes to = (κ)/(1000 × M). Since the options here use cm², the standard formula used in Step 2 is the correct choice.

Answer 1

The Correct Option is D
