What is the molarity of a solution that contains 125 g nacl in 4.00 l solution? (molar mass of nacl = 58.44 g/mol) a. 0.535 m b. 2.14 m c. 8.56 m d. 31.3 m?

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
