A 29.00 mL sample of an H2SO4 solution of unknown concentration is titrated with a 0.1122 M KOH solution. A volume of 43.22 mL of KOH was required to reach the equivalence point. What is the concentration of the unknown H2SO4 solution? Express your answer using four significant figures.

The concentration of the unknown  solution is 0.167 M.

Explanation:

Given: = 29.00 mL,     = ?

= 43.22 mL,       = 0.1122 M

Formula used to calculate concentration of the unknown solution is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that concentration of the unknown  solution is 0.167 M.

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: )
