The number of components present in a solution are

Explanation

To determine the number of components present in a solution, follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of a Solution**:
- A solution is a homogeneous mixture where two or more substances are uniformly distributed.

2. **Identify the Components of a Solution**:
- In a solution, there are typically two main components: the solute and the solvent.
- **Solute**: The substance that is dissolved (usually present in a smaller amount).
- **Solvent**: The substance that does the dissolving (usually present in a larger amount).

3. **Count the Components**:
- Since a solution consists of one solute and one solvent, the total number of components in a solution is 2.

4. **Conclusion**:
- Therefore, the number of components present in a solution is 2: the solute and the solvent.

### Final Answer:
The number of components present in a solution is 2.
