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

The prefix "milli-" means one-thousandth, so it takes 1000 milligrams to make one gram.  To convert 2300 milligrams to grams, divide by 1000, which will give you 2.3 grams.  Then, since you had 6 teaspoons, multiply the 2.3 grams times 6, which will give you a grand total of 13.8 grams of sodium.

The chemical formula of salt is sodium chloride, NaCl.  One atom of sodium will lose its one electron in its outer electron shell, causing it to become a sodium ion, Na+.  Chlorine needs one electron to complete its outer electron shell, so it accepts sodiums electron to become a chlorine ion, Cl-.  The positive of the positive ion exerts a strong attraction on the negative of the negative ion, the two bond together in one of the strongest types of bonds known, an ionic bond.  This type of bond is so strong, it takes a temperature of 800 degrees Celsius to reach its melting point.
