Calculate the molar mass (in g/mol) of the anhydrous and hydrated forms of copper ii chloride

Explanation:

Hello,

In this case, since anhydrous copper (II) chloride is CuCl₂ whose molar mass is:

We can also find copper (II) chloride both monohydrate and dihydrate as CuCl₂·H₂O and CuCl₂·2H₂O respectively, whose molar masses are:

Best regards.

thats how its supposed to be

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: )
