(a) Define the term molar conductivity . How is it related to conductivity of the related solution ?
(b) One half-cell in a voltaic cell is constructed from a silver wire dipped in silver nitrate solution of unknown concentration . Its other half-cell consists of a zinc electrode dipping in `1.0`M solution of `Zn(NO_(3))_(2)` . A voltage of `1.48` V is measured for this cell . Use this information to calculate the concentration of silver nitrate solution used. `(E_(Zn^(2+)|Zn)^(@) = -0.76V , E_(Ag^(+)|Ag)^(@) = + 0.80V`).

Explanation

### Step-by-Step Solution

#### Part (a): Definition of Molar Conductivity

1. **Definition**: Molar conductivity (Λ) is defined as the conductivity (κ) of an electrolyte solution divided by its molar concentration (C). It is expressed mathematically as:
\[ \Lambda = \frac{\kappa}{C} \]
