A solution of potassium iodate (KIO₃) has a concentration of 1.75 mol dm^-3. What volume (in dm³) of solution contains exactly 50 g?

Question

Quizplus · Accepted Answer

First, calculate the molar mass of KIO3: K (39.1) + I (126.9) + 3*O (3*16) = 214 g/mol. Then, find the moles in 50 g: 50 g / 214 g/mol = 0.2336 mol. Finally, use the concentration to find the volume: 0.2336 mol / 1.75 mol/dm³ = 0.134 dm³.
