In order to have some sense about how carbon dioxide affects concentration of carbonate ion in the water, let us assume pure water instead of seawater is used as the solvent for simplification. The composition of the total salt components of the sea water shows 0.42 g Ca2+/1000 kg seawater. Given the density of sea water 1.02 g/mL, calculate the molar concentration of Ca2+. I got 1.07x10-5 M Ca2+ when I solved it but it doesn't seem correct.

Determining the amount of sulfate ion (SO2) dissolved in seawater in the unit of molarity QUESTION Sulfate concentration in the seawater is about 28 mm (0.028 M). Take the reverse approach to the calculation procedure in the previous Question #1 (so called a backward calculation) and find a rough estimate for the volume of the seawater sample you may need to take from the beach like the one below. A 20.0 mL sample solution contains unknown amount of bromide ion...
