A solution labelled as 1 molar 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 Molarity
Molarity (M) is defined as the number of moles of solute per liter of solution. Mathematically, it is expressed as:
\[ \text{Molarity (M)} = \frac{\text{Number of moles of solute}}{\text{Volume of solution in liters}} \]

### Step 2: Classify Properties
Properties of matter can be classified into two categories:
