2. 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.
3. Determine the amount of sodium that has been actually added, in grams.
4. State the chemical formula of salt and classify the bond as ionic, polar covalent, or non-polar covalent.
