Answer:
Solutions of magnesium sulfate and potassium phosphate react to form a precipitate. What volume, in L, of 2.31 mol/L
magnesium sulfate solution is needed to react with excess potassium phosphate solution if 66.5 mol of precipitate are collected?
3 Mgso,(aq) + 2 KPO,(aq) → Mg,(PO,z(s) + 3 K,SO, (aq)
