A gas has a solubility of 1.46 g L at 8.00 atm of pressure. What is the pressure of a sample of the same gas that contains 2.7 g/L of the dissolved gas?

Explanation:

= Initial concentration = 1.46 g/L

= Final concentration = 2.7 g/L

= Initial pressure = 8 atm

= Final pressure

From Henry's law we have the relation

The pressure of a sample of the same gas at the required concentration is .

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: )
