What is the molar conductivity of $0.05 M$ solution of sodium hydroxide, if its conductivity is $0.0118 S cm^{- 1}$ at $298 K$ ?

Options:

Answer:

Solution:

$M = 0.05, k (conductivity) = 0.0118 Scm^{- 1} Λ_{m} = \frac{k \times 1000}{M} Λ_{m} = \frac{0.0118 \times 1000}{0.05} Λ_{m} = 236 Scm^{2} \cdot mol^{- 1}$
