If every quantity is expressed in SI units, then molar conductivity `(wedge_(m))`, conducitivy `(kappa)` and molarity (M) are related as____.

Explanation

To solve the problem, we need to establish the relationship between molar conductivity (λm), conductivity (κ), and molarity (M) when all quantities are expressed in SI units.

### Step-by-Step Solution:

1. **Understanding the Terms**:
- **Molar Conductivity (λm)**: This is defined as the conductivity of an electrolyte solution divided by its molarity. It is expressed in units of S·m²/mol.
- **Conductivity (κ)**: This is the measure of a solution's ability to conduct electricity, expressed in units of S/m (siemens per meter).
- **Molarity (M)**: This is the concentration of a solution expressed in moles per cubic meter (mol/m³).
