Options
- A. 143 \ ^ -1 cm^2 mol^ -1
- B. 98 \ ^ -1 cm^2 mol^ -1
- C. 124 \ ^ -1 cm^2 mol^ -1
- D. 87 \ ^ -1 cm^2 mol^ -1
Answer
C. 124 \ ^ -1 cm^2 mol^ -1
Step-by-step solution
Given concentration C = 0.2 M and conductivity k = 0.0248 \ ^ -1 cm^ -1 . The formula for molar conductivity is _m = k 1000 C . Substituting the given values: _m = 0.0248 1000 0.2 _m = 24.8 0.2 = 124 \ ^ -1 cm^2 mol^ -1 . Answer: 124 \ ^ -1 cm^2 mol^ -1
