Common table salt, or sodium chloride, has a molar mass of 58.4 grams per mole. Chlorine accounts for roughly 60 percent of this chemical's total mass.
Heavily consumed by multi-cellular organisms, sodium chloride is the chemical responsible for the salinity in the planet Earth's oceans. In addition, salt is used for a wide range of industrial applications, with uses in fire fighting, medicine, agriculture and deicing major roads.
Sodium chloride is often referred to as salt by non-scientists, but in science, the word "salt" is used for a much larger range of chemicals. The scientific definition of a salt is an ionic compound that is the result of neutralization from the combination of an acid and a base.
