How many fluorine atoms are present in 5.85 g of c2f4?

Explanation:

Hello,

At first, molecular mass of dicarbon tetrafluoride is:

Now, by applying the mole-mass relationship with the Avogradro's number one finds that:

Best regards.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

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: )
