of their molar conductivities will be
(b) 11.574
(c) 0.0864
(d) 1.852
(a) 0.54​

Answer 1

Two solutions have the ratio of their concentrations 0.4 and ratio of their conductivities 0.216. The ratio of their molar conductivities will be 0.54.

Answer 2

Two solutions have the ratio of their concentrations 0.4 and ratio of their conductivities 0.216. The ratio of their molar conductivities will be (a) 0.54

Explanation:

Molar conductivity is defined as the conductivity of an electrolyte's solution divided by the electrolyte's molar concentration, and it measures how efficiently an electrolyte conducts electricity in solution.

It is given that,

Ratio of the concentration of solutions $(C)$ = 0.4

Ratio of their conductivity of solutions $(K)$ = 0.216

To determine - Ratio of the molar conductivities $(\lambda_m)$

The necessary formula is  $\lambda_m =\frac{K}{C} ... (1)$

Substitute the required values in the equation (1)

$\lambda_m=\frac{0.216}{4}$

Complete the preceding step

$\lambda_m=0.54$  

The molar conductivities of the aforementioned solutions have a ratio of 0.54. (no units).
