(b) The measured resistance of a conductance cell was 100 ohms. Calculate (i) the specific conductance and (ii) the molar conductance of the solution
`(KCl=74.5 g mol^(-1)` and cell constant =1.25 `cm^(-1))`

Explanation

### Step-by-Step Solution

#### (a) Definitions

1. **Conductivity (κ)**:
- Conductivity is defined as the ability of a solution to conduct electric current. It is a measure of how well the ions in the solution can move and carry charge. The unit of conductivity is Siemens per meter (S/m).

2. **Molar Conductivity (Λm)**:
