Problem

The equivalent conductance at infinite dilution of the salt MX is

160.84\,\text{ohm}^{-1}\,\text{cm}^2\,\text{eq}^{-1}

. If the transport number of

\text{M}^+

is 0.40, the ionic mobility of

\text{X}^-

\text{cm}^2\,\text{s}^{-1}\,\text{V}^{-1}

is (a) 3.9 × 10 (b)

6.7 \times 10^{-4}

(c)

2.5 \times 10^{-3}

(d)

1.0 \times 10^{-3}
