What is the molarity of a solution containing 3.5 moles of hcl in 5.0 l of water?

a) 0.70 m
b) 1.4 m
c) 3.5 m
d) 18 m.

0.70 M

Explanation:

In this case;

We are given;

Number of moles of HCl = 3.5 Moles

Volume of solvent, H₂O is 5.0 L

But,

Therefore;

                   = 0.70 M

Thus, the molarity of the solution is 0.70 M or 0.70 moles/liter

put the answers   and i could answer.

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: )
