Gypsum (CaSO4·2H2O) is added to soil to enhance plant growth. It dissolves according to the following equation: CaSO4⋅2H2O(s)⇌Ca2+(aq)+SO2−4(aq)+2H2O(1)CaSO4⋅2H2O(s)⇌Ca2+(aq)+SO42−(aq)+2H2O(1) The Ksp of gypsum is 3.14 × 10−5. How much gypsum, in grams, should you add to your 5.0 L watering can to produce a saturated solution?
