What is the percentage of salt in the human body?

Answer 1

Assuming the question pertains to table salt (sodium chloride), a human body contains approximately 0.15 percent by weight chlorine and 0.15 percent by weight sodium. This means that a 70-kilogram human (150 pounds) will contain 0.095 kilograms, or 95 grams, of each of the elements in table salt. The constituents of common table salt exist as separate ions in the human body, and if we could remove them and reconstitute them into table salt, they would make up about 8 tablespoons of salt for a 150 pound person.
