When fresh water is removed from ocean water, the salts that are left behind are also a valuable resource. Over half of the world's supply of magnesium, a strong, light metal, is obtained from seawater in this way.

Ocean water contains 3.5 g NaCl by mass How much salt can be obtained from 274 g of seawater?

To find how much salt can be obtained, we need to calculate the mass of NaCl in 274 g of seawater. Since the concentration of NaCl in seawater is 3.5 g per 100 g of water, the mass of NaCl in 274 g of seawater is 9.59 g. Therefore, 9.59 g of salt can be obtained from 274 g of seawater.

How much sodium hydroxide in grams must be added to seawater to completely precipitate 86.9mg of magnesium?

To completely precipitate 86.9mg of magnesium from seawater, you would need to add an equal molar amount of sodium hydroxide. The molar mass of magnesium is about 24.3 g/mol, so 86.9mg is equivalent to about 3.57 mmol of magnesium. You would need the same amount of mmol of sodium hydroxide to completely precipitate the magnesium.
