<u>Answer:</u> The molarity of phosphoric acid is 0.05 M
<u>Explanation:</u>
A neutralization reaction is defined as the reaction in which an acid reacts with a base to form a salt and water molecule.
At equivalence, moles of acid becomes equal to the moles of base. The equation for the neutralization follows:
........(1)
where,
are the n-factor, molarity and volume of acid that is 
are the n-factor, molarity and volume of the base that is NaOH
Given values:

Plugging values in equation 1:

Hence, the molarity of phosphoric acid is 0.05 M
