To find the mass of solute in the solution, use the formula: mass = molarity (M) × volume (L) × molar mass of solute (g/mol). First, convert the volume from mL to L: 256 mL = 0.256 L. The molar mass of ammonium chloride (NH4Cl) is approximately 53.49 g/mol. Therefore, mass = 0.909 M × 0.256 L × 53.49 g/mol = 12.4 g.
