Options
- A. 1.140 10^ -2 \ ^ -1 \ cm ^ -1
- B. 1.263 10^ -2 \ ^ -1 \ cm ^ -1
- C. 1.340 10^ -2 \ ^ -1 \ cm ^ -1
- D. 1.463 10^ -2 \ ^ -1 \ cm ^ -1
Answer
B. 1.263 10^ -2 \ ^ -1 \ cm ^ -1
Step-by-step solution
Given: Resistance, R = 95.0\ Cell constant, G^ * = 1.2\ cm ^ -1 The conductivity is given by the relation: = 1 R G^ * Substituting the given values: = 1 95.0 1.2 = 0.01263\ ^ -1 \ cm ^ -1 = 1.263 10^ -2 \ ^ -1 \ cm ^ -1 Answer: 1.263 10^ -2 \ ^ -1 \ cm ^ -1
