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:
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 %
