In order to make a 750 cm³ solution of potassium iodate (KIO₃), with concentration 2.5 mol dm^-3, what mass (in g) of potassium iodate must be dissolved?

Question

Quizplus · Accepted Answer

To find the mass of KIO3 needed, use the formula: mass = concentration × volume × molar mass. The molar mass of KIO3 is approximately 214 g/mol. The volume in dm³ is 0.75 dm³. Thus, mass = 2.5 mol/dm³ × 0.75 dm³ × 214 g/mol = 401.25 g, which rounds to 401 g.
