Diffine the following mofes of expressing the concentration of a solution? Which of which of these modes are independent of temperature and why ?
`{:((a),w//w("mass percentage"),(b),V//V("volume percentage")),((c),w//V("mass by volume percentage"),

Explanation

To solve the question, we will define the three modes of expressing the concentration of a solution: mass percentage (w/w), volume percentage (v/v), and mass by volume percentage (w/v). We will also identify which of these modes are independent of temperature and explain why.

### Step-by-Step Solution:

1. **Define Mass Percentage (w/w)**:
- Mass percentage is defined as the mass of the solute divided by the total mass of the solution, multiplied by 100.
- Formula:
\[
