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.
•Determine the amount of sodium that has been actually added, in grams.
•State the chemical formula of salt and classify the bond as ionic, polar covalent, or non-polar covalent.
(2300 mg Na/teaspoon) x 6 tsp = ?mg Na.
NaCl, sodium chloride, ionic bond.
To determine the amount of sodium that has been actually added, we need to calculate the quantity of sodium in 6 teaspoons of salt.
Each teaspoon of salt contains about 2,300 mg of sodium, so 6 teaspoons would contain:
6 teaspoons * 2,300 mg/teaspoon = 13,800 mg of sodium.
To convert this to grams, we divide by 1000:
13,800 mg / 1000 = 13.8 g of sodium.
Therefore, the amount of sodium that has been actually added is 13.8 grams.
The chemical formula of salt is NaCl. It consists of sodium (Na) and chloride (Cl) ions. The bond between sodium and chloride is ionic because there is a complete transfer of electrons from sodium to chloride, resulting in the formation of ions with opposite charges.
