उत्तर
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
