Solid material that is dissolved in seawater is referred to as salts. Salts make up about 3.5 percent of
the mass of seawater. The following chart lists the major dissolved salts that are present in seawater and
identifies the number of grams of each salt contained in 100 grams of water.
Salts Most Abundant in Sea Water
Dissolved Salts
Sodium chloride (NaCl)
Magnesium chloride (MgCl)
Magnesium sulfate (MgSo.)
Calcium sulfate (CaSO)
Potassium sulfate (K, SO)
Calcium carbonate (CaCo.)
Magnesium bromide (MgBr.)
Approximate Mass (in grams per 100 grams of
sea water)
2.72

1. Use the following equation and the information contained in the chart to calculate the percentage that each
dissolved salt represents of the total mass of dissolved salts found in seawater. Enter your data in the
appropriate space provided in the Data Table. Use the data to make a Bar Graph
Percentage of the total = Mass of dissolved salts (grams) x 100
