A chemist prepares a solution c/ sodium hyposullate (Na, S, O,) by measuring out 128. umol of sodium hyposulfate into a 250. mL volumetric Mask and filing the fask to the mark with water. Calculate the concentration in mol/L of the chemist's sodium hyposulfate solution. Round your answer to 3 significant digits.

i'm pretty sure it is letter c.) car

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

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: )
