Which concentration term is least affected by change in temperature.

Options

A. molarity
B. mass/volume
C. molality
D. normality

Explanation

To determine which concentration term is least affected by changes in temperature, we will analyze different concentration terms one by one.

### Step-by-Step Solution:

1. **Understanding Molarity (M)**:
- Molarity is defined as the number of moles of solute divided by the volume of the solution in liters.
- Formula: \( M = \frac{\text{Number of moles of solute}}{\text{Volume of solution (L)}} \)
- **Effect of Temperature**: As temperature changes, the volume of the solution changes due to thermal expansion or contraction. Therefore, molarity is affected by temperature changes.
