The specific conductance of a `0.1 N CKI` solutin at `23^@ C ` is `0.012 "ohm"^(-1) cm^(-1)`. The resistance of cell containing the solution at the same trmprature was contaning the solution at the same temperature was found to be `55` ohm. The cell constant will be .

Options

A. ` 0. 142 cm^1`
B. ` 0.918 cm^1`
C. ` 0. 66 cm^1`
D. ` 1.12 cm^1`

Answer

C

Explanation

` K=1/K xx` Cell constant.
Cell constant `= K R, 0.012 xx5 = 0. 66 cm^(-1)` .
