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:
.
Calculate the concentration of a solution where
