A chemistry student is given a 10 mL sample of a solution containing chloride ions and sulfate ions, and is asked to determine the mass of each ion present in the sample. The student knows that the total mass of the solution is 12.25 g, and that the density of the solution is 1.225 g/mL. The student also knows that the mass percent of chloride ions in the solution is 5%, and the mass percent of sulfate ions is 10%. Using mass balance calculations, what is the mass of chloride ions and sulfate ions present in the sample?
