The measured volumetric flow rate of ethane at 5.00 atm absolute and 85.0°c is 5.00 x 103 l/h. using an estimated value of the second virial coefficient in the truncated virial equation (equation 5.3–2), calculate v∧ , estimate the compressibility factor z, and determine the mass flow rate of ethane in kg/h.

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: )
