Here I send you all the 3 elements that you are asking for.
Notice that first on the left you will find lewis structure, then condensed and finally chemical formula of each of the compound you enlisted.
Answer:
Concentration of the original solution: approximately
.
Explanation:
Notice that the concentration of the solution is in the unit
. However, the unit of the two volumes is
. Convert the unit of the two volumes to
to match the unit of concentration.
.
.
Calculate the number of moles of molecules in that
of
solution:
.
is a monoprotic acid. In other words, each
would release up to one proton
.
On the other hand, is a monoprotic base. Each
formula unit would react with up to one
.
Hence, molecules and
formula units would react at a one-to-one ratio.
.
Therefore, that of
molecules would neutralize exactly the same number of
formula units. That is:
.
