WebThe density of the 10.0% solution is 1.109 g/mL. Answer PROBLEM 8.3.4 The hardness of water (hardness count) is usually expressed in parts per million (by mass) of CaCO 3, which is equivalent to milligrams of CaCO 3 per liter of water. What is the molar concentration of Ca 2+ ions in a water sample with a hardness count of 175 mg CaCO 3 /L? Answer Web2 feb. 2024 · Exercise 18.5.4. The first step in the preparation of magnesium metal is the precipitation of Mg (OH) 2 from sea water by the addition of Ca (OH) 2. The concentration of Mg 2+ ( aq) in sea water is 5.37 × 10 –2 M. Calculate the pH at which [Mg 2+] is diminished to 1.0 × 10 –5 M by the addition of Ca (OH) 2. Answer.
