1. **Molarity**  
   - Defined as the number of moles of solute per liter of **solution**.  
   - Expressed mathematically as:  
     $$
     M = \frac{\text{moles of solute}}{\text{liters of solution}}
     $$
   - It is temperature-dependent since the volume of the solution can change with temperature.

2. **Molality**  
   - Defined as the number of moles of solute per kilogram of **solvent**.  
   - Expressed mathematically as:  
     $$
     m = \frac{\text{moles of solute}}{\text{kilograms of solvent}}
     $$
   - It is temperature-independent because it is based on mass, which does not change with temperature.

Thus, the primary differences are the basis of measurement—volume versus mass—and the dependence on temperature.
Molarity measures the number of moles of solute per liter of solution and is affected by temperature. Molality measures the number of moles of solute per kilogram of solvent and is not affected by temperature.
