Dear student,
According to your question and taking into consideration that you want to know about the equivalent weight of phosphoric acid. So here it is-
First draw the structure of h3po4 in which three oxygen atoms will be directly attached to hydrogen atoms,only those will be considered for the n-factor.
Here 3 oxygen atoms are directly attached to hydrogen and hence n-factor is 3.
Equivalent weight - Molecular weight/3.
