What mass of solute is contained in 256 mL of a 0.838 M ammonium chloride solution?

Question

Quizplus · Accepted Answer

The correct answer is A because the mass of solute can be calculated using the formula: mass of solute = concentration × volume of solution × molar mass of solute. The molar mass of ammonium chloride is 53.49 g/mol. So, the mass of solute in 256 mL of a 0.838 M ammonium chloride solution is: mass of solute = 0.838 M × 0.256 L × 53.49 g/mol = 11.5 g.
