A 24.6 mL sample of 0.265 M trimethylamine, (CH3)3N, is titrated with 0.391 M hydrobromic acid. The pH before the addition of any hydrobromic acid is
Use the Tables link in the References for any equilibrium constants that are required.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
