b. The actual sodium chloride content in the sea water was 2.69%. If it had been assumed that the dissolved solid(s) consisted only of sodium chloride, what percentage error would have resulted? [Caution: the answer is not 0.56%] The numbers included here are for a typical sea water sample. In addition to NaCl, typical sea water contains about 0.56% by mass of compounds (primarily chlorides) of magnesium, calcium and potassium.
