It's called iodised salt when a little bit of iodine has been added to it. Iodine is good for your thyroid gland, that's why.
Iodised salt contains a very small amount of iodine added to prevent iodine deficiency. When heated during cooking, the iodine content in iodised salt does not vaporize or sublimate significantly to create a health concern. Hence, the amount of iodine present in the food after cooking from iodised salt is negligible and safe.

The mass of the table salt can be calculated by subtracting the mass of the container from the combined mass of the table salt and the container. So, 124g - 9g = 115g. Therefore, the mass of the table salt is 115g.
From Wikipedia: "United States In the U.S. in the early 20th century, goitre was especially prevalent in the region around the Great Lakes and the Pacific Northwest.[6] David Murray Cowie, a professor of paediatrics at the University of Michigan, led the U.S. to adopt the Swiss practice of adding sodium iodide or potassium iodide to table and cooking salt. On May 1, 1924, iodised salt was sold commercially in Michigan.[7] By the fall of 1924, Morton Salt Company began distributing iodised salt nationally." Also iodates of Na and K can be added; now this practice is well known around the world and is legal in some countries. It is strange, but some crazy sectarians are against this procedure !
sodium chloride
Iodised table salt contain sodium chloride, potassium iodide (or iodate) and anticaking substances.
The healthier salt is iodised; but the sea salt can be also iodised.

Iodised salt is recommended to avoid idiocy.See this link: http://en.wikipedia.org/wiki/Iodised_salt.
Iodised salt (sodium chloride) contain iodine (as potassium/sodium iodide or potassium/sodium iodate). The concentration of iodine is 20 +/- 5 mg/kg. Iodised salt is recommended to avoid idiocy.
Salt, or table salt (NaCl) is a substance because NaCl is a compound. However, salt dissolved in water is a mixture because the sodium and chlorine ions dissociate.
This depends on the country, foods store, type of salt; in Romania the price of 1 kg fine iodised table salt is approx. 0,3 US $.

Pure salt is a compound made from Sodium (Na) and Chlorine (Cl). Its formula is NaCl and it is a pure substance not a mixture. However, most salt you purchase from a shop as' Table Salt' is iodised (for health reasons) and contains anti caking agents (to make it run). That is, it has had iodine other substances added to it. This makes Table Salt a mixture.
Thankfully it is now very easy to get non-iodised salt at local grocery chains. Brands like Kroger, Harveys, and Publix all have store brand non-iodised salt. Lawreys and Morton also sell a non-iodised salt on their website.
