The resistance of a conductivity cell containing solution at is . If the conductivity of is , what is the cell constant?

Answer and explanation

Correct answer: C.

  1. Step 1: Relate cell constant to conductivity and resistance : .
  2. Step 2: Substitute given values: and .
  3. Step 3: Calculate: .
Answer
.
Why not the others: halves the cell constant; divides resistance by conductivity incorrectly; doubles the cell constant.
