Ca, they only have two valence electrons, in order to become more stable, they would like to lose all of them
<u>Answer:</u> The molarity of barium hydroxide solution is 0.118 M.
<u>Explanation:</u>
To calculate the concentration of acid, we use the equation given by neutralization reaction:

where,
are the n-factor, molarity and volume of acid which is 
are the n-factor, molarity and volume of base which is 
We are given:

Putting values in above equation, we get:

Hence, the molarity of
solution will be 0.118 M.
