The ocean on Planet “X” has only three major ions: Ca2+, SO42- and Cl-. Calculate the average salinity of the ocean on Planet “X” if the average concentrations of these major ions are: [Ca2+] = 14.00 mmol/L; [SO42-] = 6.50 mmol/L; [Cl-] = 15.00 mmol/L. Assume the density of the ocean on Planet “X” is similar to that on Earth.
