Chemistry problem I am stuck! Please help!

If .240 g of an unknown triprotic acid (H3X) requires 18.00 mL of a .500 M NaOH solution for neutralization, what is the molecular weight of the acid? If it is a common phosphorous containing oxy-acid, what is the formula and name?
 
I think I have a balanced chemical equation of H3X+3NaOH=Na3X+3H2O but I have no idea what to do next please help.
