A solution labelled as 1 olar NaCl is kept in the laboratory. What kind of property is this molarity, extensive or intensive ?

Explanation

To determine whether the molarity of a solution is an extensive or intensive property, we can follow these steps:

### Step 1: Define Extensive and Intensive Properties
- **Extensive Properties**: These properties depend on the amount of matter present. Examples include mass, volume, and total energy.
- **Intensive Properties**: These properties do not depend on the amount of matter present. Examples include temperature, pressure, and density.

### Step 2: Understand Molarity
- Molarity (M) is defined as the number of moles of solute divided by the volume of the solution in liters. The formula is:
