Match each sulfate salt solution with the corresponding number of sulfate ion moles. Assume all salts dissolve in water.
-500 mL of 0.0002 M magnesium sulfate solution

Question

Quizplus · Accepted Answer

Magnesium sulfate (MgSO4) dissociates in water to give one mole of Mg^2+ and one mole of SO4^2- per mole of MgSO4 dissolved. Therefore, a 0.0002 M solution of magnesium sulfate will have 0.0002 moles of sulfate ions per liter. Since the volume is 500 mL (0.5 L), the number of moles of sulfate ions will be 0.0002 moles/L * 0.5 L = 0.0001 moles.
