A 17.44 gram sample of a hydrate of zinc sulfate is heated strongly in a crucible to dehydrate completely. After heating, the mass of the sample is 9.79 grams.
Calculate the molecular formula for this hydrate.

there is none because earth is stationary and flat.

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: )
