Question

Two solutions have the ratio of their concentrations 0.4 and ratio of their conductivities 0.216. What is the ratio of their molar conductivities?

Options

• 1.852

• 0.0864

• 11.574

• 0.54

Answer 1

0.54

Explanation:

`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
