• A. 5.00 mL
• B. 250.0 mL
• C. 255.0 mL
• D. 245.0 mL

Answer: (B)

Verified step by step guidance

1. Read the problem carefully: A student dissolves 5.00 g of NaCl in enough water to make 250.0 mL of solution. The question asks for the volume of the solution.
2. Understand that the volume of the solution is the total volume after dissolving the solute (NaCl) in the solvent (water). The problem states the solution volume is made up to 250.0 mL, which means the final volume is 250.0 mL.
3. Recognize that the mass of NaCl added does not change the final volume beyond what is specified, because the problem explicitly says 'enough water to make 250.0 mL of solution.' This means the total volume is controlled and fixed at 250.0 mL.
4. Therefore, the volume of the solution is simply the volume given in the problem, which is 250.0 mL.
5. No further calculations are needed since the problem directly provides the final volume of the solution.
