Number of moles of NaCl = molarity * volume of solution in L
Number of moles of NaCl = 0.025 * 0.05 = 0.00125 mole
molarity of NaCl = number of moles of NaCl / volume of solution in L
0.25 = 0.00125 / volume of solution in L
volume of solution in L = 0.00125 / 0.25 = 0.00500 L
1 L = 1000 mL
0.00500 L = 5.00 mL
Therefore, the volume of NaCl = 5.00 mL
