Question:

What masses of sodium chloride, magnesium chloride, sodium sulfate, calcium chloride, potassium chloride, and sodium bicarbonate are needed to produce 1 L of artificial seawater for an aquarium? The required ionic concentrations are [Na+] = 2.56 M, [K+] = 0.0090 M, [Mg2+] = 0.054 M, [Ca2+] = 0.010 M, [HCO-3] = 0.0020 M, [Cl-] = 2.60 M, [SO42-] = 0.051 M.
