Determining Normality

Stumbled upon a practice problem in general chemistry review book 95 g PO4 3- and it is to determine the normality of the following solutions species of interest is H+. I get that the formula to use is Molarity = Normality / n. Why is the n in this problem 3 equivalents per mole of PO4 3-. Also specifically is Normality telling us? And Molarity telling us?

Molarity x H ions will get you Normality.

Ya I figured that out
