Question

Specific conductance of 0.1 M sodium chloride solution is 1.06 × 10⁻² ohm⁻¹ cm⁻¹. Its molar conductance in ohm⁻¹ cm² mol⁻¹ is ______.

Options

• 1.06 × 10²

• 1.06 × 10³

• 1.06 × 10⁴

• 5.3 × 10²

Answer 1

Specific conductance of 0.1 M sodium chloride solution is 1.06 × 10⁻² ohm⁻¹ cm⁻¹. Its molar conductance in ohm⁻¹ cm² mol⁻¹ is 1.06 × 10².

Explanation:

`∧_"m" = (κ xx 1000)/"M"`

= `(1.06 xx 10^-2 xx 1000)/0.1`

= 1.06 × 10²
