(d) TFF

Options

A. TTT
B. FTT
C. FFT
D. TFF

Answer

To analyze the given statements and determine whether they are true or false, we will evaluate each statement step by step.

### Step 1: Evaluate Statement 1
**Statement 1:** Law of conservation of mass is valid in nuclear reaction.

- The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction. However, in nuclear reactions, some mass is converted into energy, as described by Einstein's equation \(E = mc^2\).
- Therefore, the mass of the reactants does not equal the mass of the products in nuclear reactions.

**Conclusion for Statement 1:** **False**

### Step 2: Evaluate Statement 2
**Statement 2:** On dilution, normality of the solution changes.

- Normality (N) is defined as the number of equivalents of solute per liter of solution. When a solution is diluted, the volume of the solution increases, which affects the concentration of the solute.
- As the volume of solvent increases during dilution, the normality decreases because the same amount of solute is now present in a larger volume.

**Conclusion for Statement 2:** **True**

### Step 3: Evaluate Statement 3
**Statement 3:** Molarity of the solution does not depend on the amount of solution.

- Molarity (M) is defined as the number of moles of solute per liter of solution. This means that molarity is directly dependent on the volume of the solution.
- If the volume of the solution changes, the molarity will change accordingly. Therefore, molarity does depend on the amount of solution.

**Conclusion for Statement 3:** **False**

### Final Summary of Statements
- **Statement 1:** False
- **Statement 2:** True
- **Statement 3:** False

### Answer Choices
Based on our evaluations, the correct answer is:
**(c) FFT**
