Desperate! need chemistry ! test tomorrow! to study the effect of dissolved salt on the rusting of an iron sample, a student prepared a solution of nacl by dissolving 3.038 g of nacl in enough
water to make 792.2 ml of solution. what is the molarity of this solution?
c(nacl)= m

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

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: )
