Problem: 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 18,980; sodium 10,560; sulfate 2650; magnesium 1270; calcium 400; potassium 380; hydrogen carbonate 140.(c) How does the total mass % of alkaline earth metal ions compare with the total mass % of alkali metal ions?

FREE Expert Solution

We are being asked to compare the total mass % of alkaline earth metal ions and the total mass % of alkali metal ions


Recall that mass percent is given by the following equation:

mass percent = mass componenttotal mass×100


To solve the problem, we are going to do the following steps:

Step 1: Determine the total mass % of alkaline earth metal ions

Step 2: Determine the total mass % of alkali earth metal ions

Step 3: Compare the total mass %
