Question
Choose the most correct option.
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 ______.
Options
0.54
11.574
0.0864
1.852
Solution
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.
Explanation:
Given: `K_1/K_2` = 0.216, `C_1/C_2` = 0.4
As we know
∧m = `K/C xx 100`
`∧_(m_1)/∧_(m_2) = (K_1/C_1 xx 100)/(K_2/C_2 xx 100)`
⇒ `∧_(m_1)/∧_(m_2) = (K_1/K_2)/(C_1/C_2) = 0.216/0.4`
= 0.54
