At $\displaystyle 298$ K, the molar conductivity of $\displaystyle x \%(\mathrm{w} / \mathrm{w}) \mathrm{MX}$ solution (aqueous) is $\displaystyle 123.5 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$. The conductance of same solution is $\displaystyle 1.9 \times 10^{-3} \mathrm{~S}$. The value of $\displaystyle x$ is $\displaystyle \_\_\_\_$ $\displaystyle \times 10^{-2}$. (Given : cell constant $\displaystyle =1.3 \mathrm{~cm}^{-1}$; molar mass of MX is $\displaystyle 75 \mathrm{~g} \mathrm{~mol}^{-1}$, density of aqueous solution of MX at $\displaystyle 298$ K is $\displaystyle 1.0 \mathrm{~g} \mathrm{~mL}^{-1}$ )
