To find the mass of NaCl in grams, first calculate the moles of NaCl in 25 mL of a 0.1 M solution. Moles of NaCl = Molarity × Volume (in liters) = 0.1 mol/L × 0.025 L = 0.0025 mol. The molar mass of NaCl is approximately 58.44 g/mol. Therefore, the mass of NaCl = moles × molar mass = 0.0025 mol × 58.44 g/mol = 0.1461 g, which rounds to 0.15 g.
