A solution of water (Kf=1.86 ∘C/m K f = 1.86 ∘ C / m ) and glucose freezes at − − 4.35 ∘C ∘ C . What is the molal concentration of glucose in this solution? Assume that the freezing point of pure water is 0.00 ∘C ∘ C .

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: )

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
