A freshman is currently enjoying the Arts Studio program she is pursuing at a well-known university. In her free time, she likes to skate, take salsa dance lessons, and cook. She particularly enjoys pickling and decides to pickle olives over a leisurely weekend. According to the recipe, she needs to add three teaspoons of salt to one cup of diced olives. However, she erroneously adds six teaspoons instead. Each teaspoon of salt weighs about 5g and contains about 2,300 mg of sodium.

There is 2,300 mg of sodium in 1 teaspoon. 6 teaspoons have been added. Therefore, the amount of salt that has been added is 13,800 mg, or 13.8 g. If we wanted this in mols, we just convert using the molar mass of sodium (22.99 g/mol) and get 0.60 mols of sodium. If we wanted atoms of sodium, we know that there are 6.022x10^23 molecules in 1 mol and convert that.
The chemical formula of common table salt is NaCl, since it is sodium chloride. It's an ionic bond, since it's really Na+ and Cl-
