Calculate the mass of Mg that could be obtained by the process described in Study Question 13 from 1.0 L of seawater. To prepare 100. kg of Mg, what volume of seawater would be needed? (The density of seawater is 1.025 g/cm³.)

Data given in Question 13

Although there are a number of magnesium-containing minerals, the commercial source of this metal is seawater. Treatment of seawater with Ca(OH)₂ gives insoluble Mg(OH)₂. This reacts with HCl to produce MgCl₂, which is dried, and the metal is obtained by electrolysis of the molten salt. Write balanced net ionic equations for the three reactions described here.
