7. The seven most abundant ions in seawater make up more than 99% by mass of the dissolved compounds. Here are their abundances in units of mg ion/kg seawater: chloride 18980; sodium 10560; sulfate 2650; magnesium 1270; calcium 400; potassium 380; hydrogen carbonate 140. a. What is the mass % of each ion in seawater? b. What percent of the total mass of ions is represented by sodium ions? c. How does the total mass % of alkaline earth metal ions compare with the total mass % of alkali metal ions? d. Which make up the larger mass of dissolved components, anions or cations?
